@doodledoctor,

I have suggested to look into all the items I can think that have any kind of influence.

Avast settings, display drivers, gadgets, theme software, screen resolutions, color bits (8 / 16 / 24 / 32 ), dpi font settings, task bar settings, clean uninstall under Safe Mode,…

Of course, even when it “seems” it is not needed, you should reboot after any of those changes to really see the real consequences.

Currently, I’m out of ideas :frowning: .
