From the few times I'v had this problem I have noticed 2 things:
- it only happens when you have monitors with different resolutions
- it happens when you have the "scaling" or "zooming" (or whatever it is called) activated on one off your screens
I'm not sure but I think the second one is the key one, or both need to be true.
I haven't fully tested this tho since I rarely have this.
But maybe it helps you out a bit

In addition to what already was told about different monitors and zooms or so.
Even with only one monitor there are sometimes weird things happen.
That's because full Screen does not necessarily mean full resolution.
I.e. some games are full screen but in older resolutions like 800x600 or 1024x768.
If you usually use 1920x1680 then the graphic card / monitor manager has to switch up and down depending on what is actively focused.
If you have an app that is not maximized but is using a bigger area than the full screen game resolution... it reacts weirder as it would have been maximized from the beginning.
M.D.V. 
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you

This.
I'm late to this thread, but for some reason my RSS reader marked it as unread, and I didn't remember going through it.
What you've described above matches my experience as well. If my desktop is running at 1920x1080, but a game switches fullscreen but at 1280x720 (for example), then the windows that were already opened on the desktop, and the icons on the desktop themselves, get resized/moved around to fit 1280x720 when the game takes over (if they don't fit the 1280x720 area starting from the top-left corner), and while the desktop resolution is restored back when exiting the game, the icons/windows don't follow.
Everybody passes the blame around - it's not an app's responsibility to restore the desktop layout when it exits, and once items have been moved/resized to fit the lower resolution, those new sizes/positions get committed, and no window manager that I know of (including anything on Linux) thinks it's its job to undo that.
By now it's been years I've played nothing but one game, which happens to run at the same resolution as my desktop (native 4K), and I haven't encountered that problem since. I have zero doubt that's the key.

Because Highlander and DirectX. There can be only one who has the screen context at a time, all others must detect that they lost access to it and reinitialize and redraw when they get it back.
I have lived with several Zen masters - all of them were cats.

Eh, what's Highlander? Is that the code name for the Desktop Window Manager?
The difficult we do right away...
...the impossible takes slightly longer.

You are pulling my leg, right? It's the code word for one head's length shorter: There can be only one.[^]

Ah, I see. I thought you were drawing a distinction between two different mechanisms for painting to the screen.

It is the same game as always. When two programs use the same resources, in this case the video memory and the GPU, there must be some kind of mutual exclusion mechanism. otherwise you will have race conditions or deadlocks. DirectX is quite radical. The Desktop Manager looses all rights to access to the screen and has to wait until it gets the context back. Then it's time to reinitialize and redraw everything. More than one monitor does not make it easier. A lot of games suffer from that problem as well. It took Bethesda until Skyrim to get that right without occasional glitches or deadlocks.

Lame answer, but when the program gains the context, it needs to save off the original context so that it can restore the original context when it loses context.
|
|
|
|

It does not work that way. You don't get any chance to save anything. You are informed that you just lost the context and from then on all graphics related calls will fail. by the way, how do you save a graphics processor? Don't call me lame. I'm just the messenger. Talk about it with Mickeysoft.

Accepted. My answer was based on screen context memory, which is why it was lame. Well answered!

Resolution. Windows, sadly, doesn't remember windows per-resolution. When the full-screen app changes the screen resolution, things get bad.
Run the full-screen app in your desktop resolution. Or a higher one. But not a lower one.

Pity some games can't get higher resolutions and playing them in windowed mode is a PITA.
That's why, when I play, I usually don't have any other stuff open, or if open minimized in the tray.

I get this type of stuff when using my work VM from home connected with Citrix WS. Usually works pretty swell, full screen, with 2 monitors. The other day I had been reading a page for 2 minutes, hadn't touched my keyboard/mouse. Suddenly, the 16 windows that were minimized, reappeared in a cascading fashion that made it seem like the thing was haunted or someone was dickin around with my rig.

In my opinion, Microsoft hasn't had multimonitor right since Win 7. I think their focus on managing touch screens in Win 8 and 10 had them forget how to manage more than one monitor properly.

I don't see this with the applications I run. I suspect it's primarily a game issue and frankly, game developers don't care because to fix this would take them more time to get the next best thing released.

Hello everyone ! Need quite a bit of advice. Please do understand that I am not whining or bragging at any point. Basically I am at rock bottom. I live in the UK and moved to a small town to raise my baby but partner went mental and took him away and the courts are months away due to the pandemic. It has been extremely hard. But that isnt my main point. All this time I have been doing small manual labour jobs that barely take me from one month to the other. Since all the stuff happened, I have quite a bit of free time on my hands. I am trying really hard to cope but my nearest family or friends are thousands of miles away. Anyways , sorry back to the point. I grew up doing really well at school. The kind of kid to only study exam night and ace it. Did a BA in Computing and wanted to finish my MSc in Computer Games Architecture but my mental health got in the way and I could never finish it. Ever since it has been one exploiting job after another...
So, I want to start coding or programming OR anything else you guys could advise me on.My relationship with coding is a bit tricky. I have a weird habit that when I get into something I dont know enough about, it seems TERRIFYING. My mind asks whats this symbol, or this character or this line, or this and that. But I believe if I put in hard work, I might actually be good at it. I have never put in hard work in anything due to having a chronic problem with procrastination. Anyways, what I really mean to ask is, how hard is programming or it would be for someone like me ? What should I get into ? I love the idea of creating games and have a rough idea for a retro style RPG that I always think about. What should I go with ? C# and maybe a game engine like Unity ? Or should I go into something different like Photoshop or video editting or web development ? I cant make my mind because I am really not myself. But I know I want to have a decent job, I have wasted the good years of my life but I can always fix what's to come. I am still going to continue doing a full time job but I should have free time here and there, could squeeze in 3 or so hours a day. I can sleep less, 5-6 hours is enough.
So guys, sorry for the long read but I am really lost. I want to find something to do and put my talent to it and make something out of myself. Thank you ! Please dont be mean and if someone wants to PM, sure!

We can't say: it depends on how your mind works. For me, I find it pretty easy, but I've been doing this for a very long time, so it's all "unconscious competence" for me, where you are sitting pretty much at "unconscious incompetence" - which isn't an insult, it's "trainer speak" for "not knowing how little you know", where mine is "not having to think about how to do it"*. And a "decent job" (by which you probably mean "well paid and indoors in the warm with no heavy lifting" (this is what attracteed me to the field in the first place, I must admit) takes competence: without a reasonable amount of competence (which is measured by most companies in terms of experience) you can't get anything but entry level jobs (and there are a lot of people with pieces of paper saying "I can do it" applying for them as well). Which you will be unsurprised to hear aren't interesting or well paid.
You can do it: but you need to get solid experience and knowledge of the language first and formost, and the framework second.
Photoshop isn't a job: it's an application used in many jobs, and which requires good knowledge as well and a creative flair to use properly. Not sure anyone can be taught that bit! similar problems with video editing, and web dev needs good software, together with creative flair (and a very thick skin).
I'm not trying to discourage you, but ... procrastination and 3 hours a day are not a good starting point, nor are games. Games these days are constructed by massive teams in a multitude of disciplines, and unless you are writing pretty simple Android or iOS games (in which case you probably need to learn Java or Objective C) you don't stand much chance of making much. Even with mobile games, there isn't that much profit to go around.
Good luck - I really hope you do well, whatever you decide to do.
* there are four stages of training:
1) unconscious incompetence: you don't know how to do it, and don't know that you don't know how to do it
2) conscious incompetence: you know how little you know and can do
3) conscious competence: you know you can do it
4) unconscious competence: you now longer have to think about how you do it

I was sent on a one day "Introduction to Training" training course a couple of decades ago, and that was part of it - but the company decided that it was too expensive for me to go on the whole course though. Pity, it could have been useful.

I did a course on PM and another one in Communication skills, from the PM course I only took 2 or 3 things as useful, the rest was... well common sense (at least for me, but I know it is something not usually common).
The one on communication skills was really good and taught me really useful things, but it is the hardest one to get incorporated in oneself.

There's also a stage of a form of overconfidence where you know a good amount about the subject, but not yet know how little that "good amount" actually is. Right after that phase you start asking yourself those "but what if ...?" questions. It's then that the subject matter really starts to sink in
(Could of course be part of one of those stage )

You've really got a double whammy there with both being scared of what you don't know, and uninterested in getting the ball rolling. For me, before getting a formal education in CS, any attempt at learning to program was hindered by my rushing the process. That lead to getting discouraged, becoming frustrated, and losing interest; a vicious cycle that repeated several times. I loved the idea of coding, but didn't love learning to code (at least back then.)
Now, I'm going to take a stab and say that maybe you're in that position, but it's only a guess. Overcoming the procrastination component is no easy feat imo. What worked for me was to just start with a small amount of dedicated time. Give yourself a half hour with no distractions to just focus. No nonsense, no excuses, just a half hour of your day. It might even help to make it scheduled. Scheduling keeps me focused on things that are easy to procrastinate on, like weight-lifting and hobby projects.
As for what to learn specifically, you'll really not go wrong with something like C# and Visual Studio. There's tons of support, tutorials, and places to start, though I would focus on non-game related content to start. Gaming is a different beast, but when you feel comfortable, C# knowledge transfers to the gaming world in game engines like Unity.
Finally, don't convince yourself you're "terrified" or a habitual "procrastinator." Talk to yourself in positive ways.
Good luck

Thank you Kris, that was what I needed to hear. Unlike the other reply, I am not looking to replace the head of a studio or make 3 million in 3 months. I just want to start something because everything else seems shattered, EVEN if I get nowhere. Thanks again
