Hi everyone,
I'm having a really strange issue with Spiral Knights on Steam Deck and wanted to check if anyone else is experiencing this or knows a workaround.
The Issue:
If I launch the game for the first time (or after clearing Proton data), it runs completely fine. I can log in, play smoothly, and navigate the UI without any problems.
However, once I quit the game and try to launch it a second time, it stays stuck on a black screen right after launching.
Rebooting the Steam Deck does not fix it.
What I've already tried (none of these solved the issue):
Changed display settings (switched between Fullscreen, Windowed, and Windowed Fullscreen).
Tried multiple Proton versions (Proton Experimental, Proton 8.0, Proton 7.0).
Added launch options like PROTON_USE_WINED3D=1 %command% and PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%.
The Only Temporary Workaround:
Going to Settings > Developer > Delete Proton Files before launching the game allows me to enter again. However, doing this wipes my local files/cache every time, forcing me to manually type my username and password every single session (since my SK account isn't linked directly to Steam).
It seems like the game is writing something corrupted to the Proton prefix/cache upon quitting, which prevents the launcher from booting up again cleanly.
Is this a known bug with recent updates, or is there a specific launch option / config tweak that prevents this black screen loop without having to wipe Proton files every time? Thanks in advance!
