Windows not Maximizing to Full Screen Area

Hey everyone,

I’ve had this bug ever since I switched to KDE a month ago.

I am running a 21:9 monitor as my primary display and a KVM switch from JetKVM at the same resolution.

Now I’m having this issue, where windows are not maximizing to the full screen area anymore.
This is only fixed, when I only have one screen enabled without mirroring.

Does anyone have a fix for this?

Hi! Just checking, does this happen with all windows, or only those from a certain application or app platform (ex. KDE/Qt, Chromium/Electron, GTK, etc.)? I was just thinking of issues like this that have been brought up, and was wondering if it was possibly related: Issue with maximizing Chrome/Chromium on KDE 6.1.5 / Wayland
