Steam controls this atom. It clamps Steam's 'fullscreen' size. Steam is any appid with value 769.
This is available in SteamOS 3.4 beta in Gamescope -- the UI on the Steam side isn't hooked up though.
Not easily without setting the properties manually.
Once we fix validation stuff and add acquire barrier itd make sense to open an issue on Mesa if it isnt fixed.
Fwiw --display-index does nothing on the Wayland backend. Can we even do anything there? I am not sure. Maybe pass an output to set_fullscreen? I'll look into it
It's definitely related to Decky, I was in a VC with @Sterophonick and they were going back and forth with it enabled/disabled several times, and it only reproduced with it...
I toggled overlay, over 300 times automatically while running HL2 and didnt get any crash. I just installed Decky and ran the same script, and it crashed in several seconds....
Okay, I may have found something after some more investigating with asan + Decky installed: https://github.com/Plagman/gamescope/commit/4f62e5d18ba20156348684cbebf29fc8b19c8745 ~~This may fix the issue people are seeing. I am seemingly not getting crashes...
I think its just interfering with the timing of things making a bug that has the potential to happen but doesn't end up surfacing. When the overlay opens, two 1x1...
I also tested if we hadn't processed creation fully either, by flushing wayland stuff before set_wl_id was called and that wasn't it either :thinking:
