white bar above firefox

more options

Heya!

When using Firefox (newest Version) in full screen I'm getting a white bar above firefox shown on the monitor above. (Screenshot attached). This only happens in full screen mode. Thing's I've found out while trying to fix this:

- It disappears when I use F11 to fullscreen the website. When disableing the fullscreen, the bar reappears, but turns black (wtf?) - When I'm enabling the titlebar the white bar also disappears, but I don't want to do this since then I'm having a big white titlebar which is even worse

It's just an optical error but a fix would be highly appreciated. Things I tried yet;

- start in safe mod - clean reinstallation - disabled windows tablet mode - disabled hardware accleration

Note: this only happens in Firefox, all other programs works fine.

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting for changes to take effect.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

Nope, hasn't changed anything.
