Weird mouse cursor behavior with dual monitor setup in KDE plasma

Stef99 · 2025-10-23 14:16:12

Games on steam without PROTON_ENABLE_WAYLAND=1 (Im using proton-GE) have a issue where if i click on the second monitor, the game window will minimize all the time, nothing seems to fix it other than setting the game on windowed settings. With PROTON_ENABLE_WAYLAND=1 this doesnt happen but the mouse cursor is not restricted to the main monitor, it escapes to the second monitor if the mouse cursor is moved to its side and unless I restrict the mouse input via winecfg with protontricks, this doesn't stop.
I did some testing and in the flatpak version of steam this doesn't happen and it works just fine which leads me to believe theres something wrong with kwin and plasma that makes this issue happen. No window rule has been set for anything and this has been happening since plasma 6.4.
Any ideas? Maybe I installed the wrong drivers?

Hi,
I had also some issues, but not exactly like yours.
I opened the system settings and opened the "windows rules" (I hope it is called that way in english). There I made a new entry, like "steam" or the exact game name. I started the game, switched to the "windows rules" and there is a button bottom right to scan the actual opened screens. I click it, click on the "game screen" and than you can see all variables for the actual one.
For me it was a problem, that the game was never in full screen. So I opened the value for full screen and said, that this is forced to be all the time.
I hope you can find something that helps in there for you.

Stef99 · 2025-10-25 09:59:46

Tried a few things on window rules and nothing so far. Will try a reinstall, maybe test a few things on both flatpak and pacman steam and see what might be the cause.

Games on steam without PROTON_ENABLE_WAYLAND=1 (Im using proton-GE) have a issue where if i click on the second monitor, the game window will minimize all the time

Does it actually appear as minimized in the taskbar or just disappear?

"click on the second monitor" is likely equivalent to the window losing the focus, thus the fullscreen layer - this might hinge on the (multiscreen) focus policy?

Stef99 · 2025-10-26 09:11:15

It appears as minimized in the taskbar when I select anything on the second monitor as in losing the focus. This doesn't happen on a game launched as a native wayland application so I don't know the reason as to why.
Unrelated to the topic but maybe give a hint as to whats happening is any game launched on vulkan it flickers like crazy but stops when selecting the second monitor or if I uncheck on the game's icon on the taskbar the fullscreen. All games also by default launch on border less window instead of fullscreen but I don't know if thats something normal.

seth · 2025-10-26 16:14:34

Are other xwayland clients affected, eg. xterm or "MOZ_ENABLE_WAYLAND=0 firefox" (make sure to kill all firefox instances first) - notably does the latter behave differently depending on the fullscreen state?

Stef99 · 2025-10-26 18:06:37

Heres a video demonstrating the problems. https://streamable.com/nz7kvm (WARNING: flickering is included, anyone with epilepsy be aware)

What happens on proton experimental and Proton-GE running Xwayland is that when you click on the second monitor as shown, it minimizes. On Xwayland the cursor is locked as it should be with it being only unlocked when the game is paused. Games on Vulkan don't flicker at all and work as they should with only a quick black screen when selecting the second monitor but its fast enough to not be a huge issue.
Now on Wayland (Proton-GE) the minimize problem doesn't exist but the cursor is not locked on to the main monitor and if moved to the side of the second monitor (left for my case) it will escape. Some games its locked and works for the most part but others (most games) it doesn't. For some games setting them on "Border-less Window" solves the problem. Now Vulkan on Wayland flickers a lot but after searching found this issue is caused by something KDE related but im not sure.

The main question would be whether the behavior is specific to
* steam
* xwayland
* fullscreen xwayland
clients, see my previous comment.

But from your video: do the outputs overlap?

Stef99 · 2025-10-26 22:29:38

The issue when using wayland is happening on steam and bottles, have tried playing on heroic games using geproton and wayland and it didn't happen there but it was just one game.

Xwayland Issues are: clicking or selecting anything on the second monitor minimize the window.

Wayland: 1)Cursor isn't frozen on the main monitor and can escape to the second one. 2) Games running on Vulkan flicker both of these on some games can be fixed if set on border-less window mode. The issues appear on fullscreen only.
For more clarity on the vkbasalt hud on to the right on the bottom shows if its running wayland or Xwayland. Sorry if it doesn't appear clear due to low quality.

But from your video: do the outputs overlap?

You mean the screen appearing like that on to the main monitor? No I just set it that way in OBS to show the POV of the second monitor.

seth · Yesterday 08:40:19

The issues appear on fullscreen only.

Are random other xwayland fullscreen windows affected? Doesn't have to be a specific browser, any X11/xwayland fullscreen window will do - the point is to determine whether that's a steam or a kwin bug.

Stef99 · Yesterday 09:03:08

Tried setting both Xwayland and Wayland native apps like firefox, spotify and discord full screen and I can't replicate the issue as they are working fine. Seems like a steam exclusive issue.

SDL_VIDEO_MINIMIZE_ON_FOCUS_LOSS=0

Stef99 · Yesterday 14:37:09

SDL_VIDEO_MINIMIZE_ON_FOCUS_LOSS=0 didn't fix the issue but setting the game to borderless did fix it and no longer minimizes. This was on Xwayland. Honestly I don't know why it has such a high fixation for borderless, I think I have exhausted the things to test here other than trying this on a complete new arch plasma set up.

seth · Yesterday 15:01:22

How and where did you export that?
The environment variable looks too obvious to not be relevant…

Stef99 · Yesterday 17:16:31

From the link provided? I set it on the launch options for the game as SDL_VIDEO_MINIMIZE_ON_FOCUS_LOSS=0 %command%. Like I said im just throwing whatever sticks and might fix the issues, at this point gaming via steam has become an annoyance than anything.

FWIW something whose entire purpose is to avoid such focus change gotchas is gamescope, maybe consider trying that? That said one time I've seen that happen is when "other" windows cross over the monitor border, e.g. a browser window or so that's accidentally not maximized to the proper screen border but "slightly" larger and "bleeds" into the fullscreen monitor where a game is running, make sure these conditions aren't the case. also "non standard" scaling factors between the monitors potentially? Also since xrandr on xwayland might not have the full picture, what output do you get from

I have tried gamescope but gamescope basically disables wayland and uses Xwayland by default, haven't found an option that forces it to use wayland natively.

Try

export SDL_VIDEO_MINIMIZE_ON_FOCUS_LOSS=0
steam

I have tried gamescope but gamescope basically disables wayland and uses Xwayland by default

But isn't the focuslossminimization an xwayland-exclusive issue itfp while native wayland (for proton, afaiu steam itself will run on X11/xwayland anyway?) in the first place?

Do the kwin rules allow you to prevent clients from self-minimization?

 export SDL_VIDEO_MINIMIZE_ON_FOCUS_LOSS=0
 steam

Didn't work. Gamescope does work in restricting the mouse but I found a new method granted you sacrifice any mouse movement outside the main monitor (just as it happens with gamescope) unless you do alt+tab. Via protontricks selecting winecfg, input and selecting "automatically capture the mouse in full-screen windows" will prevent both any minimizing and the cursor escaping. Works the same in wayland but I would rather have the ability to move the mouse when the game is paused.

I also tried to prevent any minimizing via window rules and for some reason the game goes completely black as shown in this video. https://streamable.com/x763fj

for some reason the game goes completely black

The client still "minimizes" internally, kwin just keeps the window up.

Running google on this insanity, try to "export SDL_HINT_VIDEO_MINIMIZE_ON_FOCUS_LOSS=0" (nb. the extra "HINT") though strings only finds SDL_VIDEO_MINIMIZE_ON_FOCUS_LOSS and only in SDL3…

I found out that the borderless window setting also fixed the minimize problem for Xwayland other than the cursor problem for Native wayland. Only found one game where this doesn't happen with wayland which the cursor still escapes but I guess I can make do with just that game not working, maybe its a kwin bug after all that Ill just have to wait for it to be fixed.
A minute ago I was testing with half life 2 and found when disabling "wait for vsync" it would change the present mode to "IMMEDIATE" from "FIFO" it would fix the cursor problem immediately but other games I tested didn't have this issue between vsync.
I guess now the only issue I have is with vulkan flickering on wayland fullscreen (borderless unlike the other games exposes the taskbar which is annoying, im looking for a workaround for this) but I think thats a GE-PROTON issue than plasma.

Yes, you're using a pseudo-fullscreen mode where it's likely to behave more like a normal window (as it is)
Does switching from VK_PRESENT_MODE_FIFO_KHR to VK_PRESENT_MODE_IMMEDIATE_KHR not impact the flicker at all (I'd see that much rather than impact on the mouse capture behavior…)
