I can't open windows or apps while playing

Hi friends.

I’m using CachyOS KDE with a GTX 1050 Ti. All my games work perfectly, both Steam and non-Steam games.

I usually play non-Steam games from my Steam library, launched using CachyOS Proton (it’s the best Proton version I have, and all my games work fine, so I don’t want to use another one unless absolutely necessary).

But when I minimize the game and try to open a browser, a program, or anything else, it glitches.

For example, if I open Firefox or LibreWolf while the game is minimized, it stays open as a new window, but it looks like a visual glitch, and I can’t see anything. I can close it with Ctrl+W, and it responds, but I can’t see the window because it’s glitched.

Sometimes apps don’t open at all or they just get stuck loading. And sometimes they do finish opening, like in the case of GameConqueror.

I’m using my default CachyOS; I haven’t made any major changes or anything. I’m not sure if this has always happened. I can usually have LibreWolf open if I launch it before starting the game. But if I try to open a private window or another app, I get this error.

Thanks in advance for your help.

Did you install enable these tweaks?

I doubt this will help much, but of course, it is worth a try, if OP does not mind to install a bag full of packages…

You may achieve the same with

sudo pacman -S cachyos-gaming-meta

But as I mentioned: I doubt this will resolve the issue. I never installed this meta-package and I never experienced such an issue (which does not mean anything, of course).
