XWayland has incorrect resolution

Hi, I'm using GNOME on Wayland with 175% fractional scaling on a 2560x1600@90 display. When using Steam through XWayland, MangoHUD shows me that my resolution is set to 2928x1830 instead of my monitor's native resolution, which I can confirm via

xrandr

. I tried setting my resolution to the correct one using

xrandr --output eDP-1 --mode 2560x1600

but it shows this error:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  7 (RRSetScreenSize)
  Serial number of failed request:  21
  Current serial number in output stream:  22

Is there any way I can force the resolution? This has caused some issues with games where I can't force a native resolution.

Edit: running via gamescope is a workaround for this.
