gamescope/scb issue: before i go HAM w/ debug copy pasta, TL;DR: last couple months gamescope/scb fails 100% (all games) under Steam’s runtime / KDE Wayland + NVIDIA as nested compositor via steam launch options (Wayland, X11, DRM, SDL all end in “Primary child shut down / Broken pipe”, libseat errors/LD_PRELOAD conflict). since i have little idea what i'm doing, i'll add
occurred as possible fix in case that could be a hint for someone who knows what theyre doing.
FOR CLARITY: Gamescope DOES work as intended via host terminal. So clearly this is not a personal emergency. But my OCD requires I obsess on everything no matter how pointless before doing anything else no matter how important. any guidance/troubleshooting; whether this is a known Bazzite/NVIDIA/Plasma 6 gamescope thing unrelated to my relentless breaking everything; or a recommended config/workaround beyond “use X11 session” - it always worked w/o x11, until it didnt, which i find sus bc this broke during a rare spell of me doing minimal unnecessary fiddling - would be big appreciated
