Linux dual monitor cursor escaping

Community Technical Support Hardware, Driver Problems & Advice
1

I have spent a not insignificant amount of time trying to get the cursor to stay in the game window on my dual monitor setup, to no luck. As soon as there is a cursor in the game, it will escape to the second screen. As long as the mouse acts as the joystick (circle on screen) everything works fine but when I get a proper mouse cursor it can escape.
System info:
Arch 6.13.17-arch1-1
Plasma 6
KWin
Xorg
Nvidia driver version 570.124.04 (I have been trying to get this to work since December and none of the driver versions since December made any difference here)

I have tried all the launch options out there that don’t require gamescope since game scope refuses to work for me. I have tried to set my xorg.conf to use separate screens with absolute and relative positions. I honestly don’t recall all the small things I did to get this to work in some way but I have pretty much exhausted every resource I know.

I was especially disheartened when I read that this issue is apparently fixed, since it clearly isn’t.

So, anybody willing to help me out here would be really appreciated. I am at my wits end. If you need any logs or other info feel free to ask.

Current launch options:

gamemoderun mangohud PROTON_ENABLE_FSYNC=1 PROTON_ENABLE_ESYNC=1 PROTON_FULLSCREEN_CURSOR_GRAB=1 %command%

Current xorg.conf(I am aware that it is messy and repeating stuff but it works - YES I AM SURE IT WORKS!):

Hello @ZeroKey,

Looking at your launch options I’m assuming you have WT installed through Steam? In that case I’m assuming you have the Native Linux client installed and your not running the Windows client through Proton?

Yes, I am using the native client. Some of those launch options are left over from just trying fixes. I even re-downloaded the game (which is why my reply took so long - game is quite big at this point), to make sure that I’m using the native client. As soon as a cursor is visible I can just move off to the right to my second screen, click and the game minimizes. I don’t have this issue with other native or proton games. Otherwise I would’ve assumed this might be a compatibility or even driver issue, as Nvidia isn’t the greatest in terms of Linux support but War Thunder is the only game that does this.

If you need any further details on my system, logs or what ever, I’m happy to supply those.
