Opera browser, full screen about half the size in Youtube

My last test was even on a Kubuntu 20.04 which has been upgraded from 19.10…

Tested again with changed global scaling (on a Lenovo M720s this time, Kubuntu 20.04).

Still simply works:
Opera (68.0.3618.125) shows exactly the same as Firefox (76.0.1) in Youtube, absolutely no differences in video sizes…
Global scaling is set to 125%.

Well, maybe I'll reinstall Kubuntu.

Not here (Neon 5.18 User, Opera 68.0.3618.125).

Whatever zoom I have it goes "full" fullscreen.

[EDIT] I just tried it on 20.04. Opera 68.0.3618.104. No problems whatsoever :·/

The problems happens when the global scaling is increased to 125% and more. 100% is too small for my eyes. Is this the same with KDE Neon?

Works correctly here:
the current Opera shows exactly the same as the current Firefox in Youtube, no differences in video sizes.
Global scaling is set to 100%.

Just tested it on my desktop computer (Kubuntu 20.04).

Display global scale 1.25, screen: 1920x1080px, Opera browser shows about 1/2 size in Youtube. It showing correct in Firefox.
