KDE Fullscreen invading other monitors

[uphiago]

I am currently using Kubuntu with KDE, and I'm experiencing an issue with fullscreen applications, such as YouTube videos, invading my second monitor. Specifically, when I switch a video to fullscreen on my primary monitor while the browser window is not maximized, the fullscreen video extends slightly into the second monitor and also invades a bit of the bottom of the screen. This issue does not occur when the browser window is maximized before going fullscreen.

I am in a clean installation, and this still hapenning



Operating System: Kubuntu 22.04.4 LTS
Desktop Environment: KDE Plasma 5.24.7
Kernel Version: 6.5.0-35-generic

Are you logging in to the Desktop with Plasma X11 or Plasma Wayland?

Now I noticed that this is only happening in Chrome. I tested it in Firefox, and the same thing with the fullscreen invading a bit of the other screen did not happen.

Per chance is your browsers default resolution set higher than 100%, like 110% or 120%?

TinyTim it's not. I have also tested with Wayland, workaround fixes, and all the stuffs... but still the same.
