- Closing ALL windows on all screens fixes the frozen screen (so does logging out/rebooting).
- Killing and restarting polybar makes polybar clickable again on the frozen screen. All other windows on the frozen screen will still be unresponsive.
- I tried screensharing with compton disabled
- I tried screensharing without Nvidia's DRM KMS
- I tried running Firefox in safe mode
- I tried disabling hardware acceleration in both Firefox and Discord
- I tried only connecting one monitor instead of 3
- I tried using i3 instead of bspwm. i3 only shows the windows and 'Entire screen', which would show all screens if more than one screen is connected. I can't pick a single screen.
- I tried using awesomewm, same result as i3.
