Are you using the Wayland session with a scale factor that's not 100%, 200%, or 300%?

I have a Laptop with a scaling factor of 125%, but this problem also exists on my Main PC where the scaling factor is in fact 100%. That's where i made the screenshot from.

I noticed that this only happens with the Breeze Theme...
Comment 5 Nate Graham 2023-02-22 14:00:29 UTC 
Wayland or X11?

Is it fixed with Plasma 5.27.1?

I'm running Wayland, and it's not fixed with 5.27.1.
Comment 7 Nate Graham 2023-02-22 21:05:40 UTC 
Ok, that means this is Bug 465158, which should be fixed for 5.27.2. :) Issues like these are caused by one of those two bugs.
