[Solved] Strange Firefox color issue within Win10 VM

MarkusA1 · Mar 26, 2018

Hy,
after updating Firefox to 59.0.1 x64 it shows strange behavior in terms of coloring. I already changed the default color templates and switched Parallels VSync on/off. Anybody experiences the same issue and has a solution for it? Please have a look at the attached screenshot. My Parallels version is 13.3.0. (The same firefox version works on Mac btw.)

Best regards

Hy Aj,
I reinstalled ParallelsTools, but it didn't help.

This issue seems to be within the Mozilla Firefox itself. kindly try this steps and check if it helps ( change the dark color: 3-bar menu (or 'Tools') => Add-ons => Themes)
and choose the light theme.

Already done that, no change. -.-

Ok, I solved it. Was apparently a Firefox problem, as the hardware acceleration was active. Turn it off, restart Firefox and it's gone.

Best regards

Thank you for this hint, it also did help at my side with Windows 7 VM on FF 70.0.1 (64-Bit)
