...and please test if it works if you disable the hardware acceleration in options/advanced/general followed by a Firefox restart.

I disabled hardware acceleration, but the Problem still appears.

The graphics Bug appears if i have for example 2 Browser windows opened, go to the 1st Window, go into private mode(windows close automatically), return from PM(windows open again automatically) - then the bug appears on Window 2.
If i have opened only one Window before switching to private mode i don't get the Bug.

Could you try your steps to reproduce (STR) in basic troubleshooting mode, please:

1) Start Firefox in safe mode (https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode) then apply your STR.


2) Create a new profile (https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles) then apply your STR.

Does it work normally in each case?
