Please describe your issue in as much detail as possible:

Whenever I am in Desktop mode after about 5 to 10 minutes the screen freezes.
Doing a sleep/wake cycle unfreezes the screen but only the opened programs will respond to inputs, the desktop or app tray will do nothing.
Only thing I changed are the screen scaling (from 100% to 150%) and the floating app tray option (although it happens with this option enabled too).

Steps for reproducing this issue:

1. Switch to Desktop mode
2. Stay in Desktop mode doing nothing or just open some apps
