White borders in the firefox window

Firefox トラブルシューティング

I have white borders around the edges of my firefox. I think this might be a firefox problem since no other application in Windows 10 seem to reproduce this issue. The problem is not visible on white background websites, but as soon as there is a color along the edges of the website I notice a tiny white border along the ages of the firefox window.

I've attached a screenshot as well.

I've noticed another thread https://support.mozilla.org/en-US/questions/1176773 that seems to have the same issue. The solution in that thread was to move the taskbar and see if it works, in my case it did not.

Weird, the attachment didn't get saved. I've attached it again below.

EDIT: You can see the problem more clearly on darker websites like imgur, i've uploaded it at the following link: https://imgur.com/a/ExChB

Sorry, the attached version only shows the white border on the bottom because of the white website background.

Hi, same problem here. Seems to only happen on my 4k Monitor, maybe a DPI-scaling problem? Do you run 4k aswell? Also when I fullscreen for example a Youtube video the border seems to stay the color of Video when I minimize it again.

Edit: For me behaviour changes when I use different compatability options regarding DPI-scaling. Not a solution however since Text is washed out with options that dont produce white borders.
