Screen tears, invalid background superimposed

Posted

FF 66 running on Fedora 29 KDE spin.

See the attached sceen shot. When I first open FF in maximized mode, the screen tears in the middle. Also, it displays a part of the screen that completely does not belong to Firefox (in the attached example, it is from the Thunderbird screen which is now background). The minimize/maximize/close buttons shown belong to Firefox, not Thunderbird.

If I resize FF using the buttons, then maximize again, it displays correctly.

Weird, huh? JimR

Is this with many websites, some, a few?

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Are you possibly using code in userChrome.css that is malfunctioning and could be causing this?
