Hmm, you could try using scopebuddy, which comes included with Bazzite. You can include any config options in there if you want, but specifically it supports options for automatically configuring width and height, and you can add more arguments as well. Final command here might look like:
scb --force-grab-cursor %command%
I also use a lot of custom configs, for example I’m tinkering with Wayland atm, but keep a gamescope config I use like this:
SCB_CONF="gamescope.conf" scb %command%
The shorter syntax is really nice, and it’s nice to be able to tweak a bunch of global options like PROTON_WAYLAND and PROTON_ENABLE_HDR without having to manage huge commands in Steam.



Very nice! Sable was actually the first game I played through on Bazzite myself!
Game’s a bit janky (it was janky on Xbox too, when I played it there years ago, with exploration stuttering so badly I vowed to return on PC later), so it was a little stressful in that I wasn’t sure if the issues were due to the game’s code or something with Proton, etc😆
But overall a wonderful experience, and an impressive indie debut. I stuck with it until I had all masks this time around!
