gamescope Cursor not locking (not respecting --force-grab-cursor)

trafficstars

When using --force-grab-cursor, the cursor is initially grabbed until another window or workspace is interacted with, then the cursor is not locked when back in gamescope. Without the --force-grab-cursor argument, the issue was still present, some games fixing the problem by opening and closing the pause menu, others not. There is also a window border which was not present beforehand, but probably irrelevant.

OS: Arch Linux
Kernel: 6.8.9-zen1-1-zen
Hyprland latest git
Using latest git - aur gamescope-git package

I have the same issue still, Final Fantasy XIV basically became unplayable for me since I can't reliable move with mouse only and i keep getting turned around and running the wrong way.

It even used to work correctly without --force-grab-cursor

I found similar issues here https://github.com/ValveSoftware/gamescope/issues/1181 and here https://github.com/hyprwm/Hyprland/issues/5076 , but these were fixed using --force-grab-cursor which doesn't work.

I don't think this is our bug, it works on every other compositor I tested just fine.

I am using niri on archlinux and it worked fine until the last package update (3.14.3). i have since switched to the -git version and it is still broken for me

Here is an example i recorded, at first just left clicking and the camera moving without input, which happens twice at the start of the video, then i walked around a bit and it happened with both left & right click simultaneously as well at the end of the video. This was working fine in a previous release of gamescope with the same compositor, unfortunately I did not take note of the version that was last working.

Same here on archlinux using plasma6 wayland session. From version 3.14.3 onwards --force-grab-cursor doesn't work anymore.

Hi I have the same problem in War Thunder. I use Arch with Plasma 6, Wayland and dual monitor.

I have managed to find a workaround like a user sugested in ProtonDB.

So I downloaded an older version and downgraded the package with: pacman -U

So far everything it worksfine, maybe it also works for the version 3.14.2.

I found similar issues here #1181 and here hyprwm/Hyprland#5076 , but these were fixed using --force-grab-cursor which doesn't work.

I can confirm that since that hyprland issue has closed, any gamescope release past 3.14.3 has broken --force-grab-cursor for me

Turns out my issue was a Hyprland one. Downgrading to Hyprland 0.39.1 looks to have fixed the issue for me. Sorry for the inconvenience. Looks like others in this issue seem to be having slightly different problems so I'll leave this open for now as theirs still fit the title description, unless anyone wants otherwise. Thanks for the help.

Looking into this currently. More info in https://github.com/hyprwm/Hyprland/issues/6159.

It's not only Hyprland, Plasma6 as well. 3.14.2 is the last working Version.

Edit: Looks like it works again for me. Using Lutris with UMU (gamescope 3.14.29).

Encountering this under X11 running KDE Plasma 6.1.0, did previously work on Plasma 6. Seems to happen when games allow cursor movement like in menus. For War Thunder this is a problem, it never tries to bind the cursor properly on linux, previously gamescope resolved this, now its unusable on linux again :(

Gamescope version 3.14.18-2.git.20240528.420eb91.fc40

why isn't there a simple hotkey like SUPER+G available for forced mouse grab beside "Super + G toggle keyboard grab" ???? I can't understand. Shall i create a PR?

I just had this show up for me after upgrading from 3.16.1 to 3.16.3.

After downgrading back to 3.16.1 --force-grab-cursor works for me.

Edit: I am using Wayland KDE on Manjaro Linux

Can confirm, was having this issue with xcom2, downgraded from .3 to .1 and now it captures cursor correctly.

Same.

3.16.2 also works. (Arch + hyprland)

Still broken in 3.16.4 as well.

Apr 18 '25 09:04 jarrard

Since this will be a year old in a few days I'd like to chip in as well.

I can confirm that 3.16.4 is broken. I can confirm that 3.16.2 does work.

Maybe will need to do a debug between these versions ourself to find the exact bit of code that does it, then produce a fix patch ourselves. I've done it once before years ago, going to need to relearn how to do it as I forgot, pretty basic github stuff but!
