There is a black box on the top left corner whenever firefox is maximized. This problem appeared when I got my new computer screen (Asus 27" TUF Gaming VG27AQ1A, 170Hz WQHD). My old computer screen (23.6" VE247H LED, Full HD, 2ms, 10M:1) didn't have this issue.

Any help how to fix this issue?

Hello,

Try running Firefox in Troubleshoot Mode to see if you theme causes the issue (this mode temporarily disables all the add-ons).

Does the problem persist in Troubleshoot Mode?
