• Description:
  The issue is pretty simple to explain.
  Most of the time when i'm disabling my secondary right monitor (DP-2 / Acer Technologies XB283K KV) via hotkey bindsym $mod+Shift+F12 output DP-2 toggle sway does turn off the monitor but also shows a completely greyed output on the main monitor (DP-1). In that case i cannot to anything and it even looks like sway crashed.
  However, sway still runs and i've found a workaround to get the desktop back. I just need to switch to another VT and back (via CTRL-ALT-F5 for example) and i have my desktop again.
  Afterwards i also can add (toggle) my secondary monitor again without problems.
  Also, it doesn't happen all the time. (but lets say 90%). After a clean start of sway i can fairly simple reproduce it, but sometimes it works without this issue, but i didn't found a clue what could be different when it works..

Please note, this is NOT a regression to 1.9. This issue already happend with 1.9. I just wanted to wait for the final 1.10 release to see if 1.10 might fix this. Also, as far as i can remember i always had that issue.

I've added a debug log file were i've only logged in and turned off (got grey screen), switched VT and turned on the monitor again.
