I'm having the same problem
i think that i finally resolved that by deleting the vrappconfig folder & steamvr.vrsettings file under ~/.local/share/Steam/config/ (might be worth it to close steam before doing that)
same bug
Nothing extracted yet.
Describe the bug
SteamVR Settings window is black screen when launching SteamVR.
This issue is more problematic than it seems since it seems to break inputs when in-game
It's worth noting that SteamVR's ui inside the headset is working fine

Expected behavior
The Setting window should show up correctly & in-game inputs should work
