firefox glitching

Operating System: Manjaro Linux KDE

KDE Plasma Version: 5.12.5

KDE Frameworks Version: 5.46.0

Qt version: 5.11.0

VGA driver: amdgpu

I've noticed a strange behaviour on how Firefox(v61) loads his window when not maximized. 
I have this problem only with Firefox and Firefox Developer Edition. 

I've already filed a bug at bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=1469267#c0

On my computer black borders appear even when Firefox 62 is started maximized.
See my screenshot taken on Arch Linux running Gnome Wayland 3.30, intel modesetting driver. Therefore I think it's a Firefox bug.
