Outside of the sandbox, it seems to work fine (no errors). This bubble has [wayland] and [x11] permissions, as well as [direct_rendering].

Hello @odomingao

I tested it on my machine by running the gamescope -- glxgears command inside sandbox and it seems to work fine.

It did also print some warnings about xkbcomp but it seems to run fine anyway:

The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning:          Unsupported maximum keycode 708, clipping.
>                   X11 cannot support keycodes above 255.
> Warning:          Could not resolve keysym XF86KbdInputAssistPrevgrou
> Warning:          Could not resolve keysym XF86KbdInputAssistNextgrou
Errors from xkbcomp are not fatal to the X server

Hmmm. This also only seems to happen with the system version of gamescope (arch package). I tested with Bottles and Steam and their gamescope works, but launching gamescope directly doesn't.

My bad, this was an issue with apparmor.
