Mouse isn't captured in Dying Light using Gamescope

[Valmar33]

When I run Dying Light within Gamescope, the mouse isn't being captured, for some reason.

Running Gamescope master, by the way. Issue doesn't occur when not using Gamescope.

I have the same issue, gamescope-git 3.7.r1.g667d8af-1 on Plasma Wayland. I tried Dying Light on Linux and Proton 5.0-9/5.13-1, but the mouse was not captured.

The same issue I've seen in Serious Sam Fusion 2017 and I believe it is happening as well with all games that show the Feral launcher.

Operating System: Arch Linux
KDE Plasma Version: 5.20.0
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1
Kernel Version: 5.9.1-arch1-1

Interestingly, at least one time my mouse was captured in Dying Light (Linux) after starting it ~15 times.

Can you check whether 2922d96 helps?

Doesn't help, sorry. :(

Hm, I can't reproduce with gamescope -e -- steam -tenfoot -steamos. Tried both Dying Light and Serious Sam. How are you starting gamescope?

One way I think I've managed reproducing is force-killing steam (pkill -9 steam) and then running it again. This will display a dialog "Verifying installation", then hide the gamescope window, then open it again with steamos. Steamos won't have the mouse captured when started this way.

Also tried reproducing with this:

gamescope -- sleep 9999 &
export DISPLAY=:1
glxgears
# Kill glxgears, then start it again
glxgears

This hides and re-opens the gamescope window, but the mouse will still be properly captured.

I open Steam, and then run Gamescope via a script that sets up a bunch of environment variables and stuff on a game-by-game basis, and then finally runs

gamescope -w <width> -h <height> -W 1920 -H 1080 -r <fps> -- mangohud <path-to-proton-binary> steam.exe <game-binary>
