Having the same problem ... The following happens: 1) Log in - compositing has been disabled (and cannot be re-enabled if I remember correctly) 2) Then log out - display freezes (black screen/displaying terminal content/...). The system can still be rebooted using SysRq combinations/executing "sleep 300; sudo shutdown -r now" in a terminal before triggering the crash/... 3) Reboot and log in again - one plasma panel is corrupted (see screenshot), the other one looks as if compositing was disabled (according to the settings it is enabled though); after toggling compositing, the panel is displayed correctly
