Cursor can't be locked to a screen when in game

Hello Cachy people!

When in game in fullscreen or windowed, using any game with steam or heroic the cursor can’t be locked to the screen my game is on. I have a 3 screen configuration and it has always worked fine before. “–force-grab-cursor” or any ingame option don’t help. Very annoying when I play something like an FPS for example.

I’ve had this issue for a few days now and I can’t find a solution to it. I’ve started my linux journey 6 months ago so I’m relatively noob. I’ve made many mistakes and learned a lot from them so maybe I did something wrong?

Any idea where to look at? If I need to reinstall something maybe?

So I just reinstalled Cachy and I still have the same problem using any game with steam or heroic. My install is basically vanilla with “Install Gaming packages” and Mission Center.
I tried a second mouse just in case but it didn’t change anything. Same with different screen placements.

I remember the problem started the same day as this one: 4/4/2025 CachyOS KDE Qt 6.9 Update - Graphical Boot is Stuck in Terminal with '_' cursor
Correlation is not causality but maybe knowing that could help.

when i have some time I’ll try installing bazzite to see if it works or not.

If you have any idea of what I should try/do, please tell me.
