Stacktrace, and some system logs

So, Plasma has a feature where you can "snap" windows to the left, right, top of the screen. Heck, I think you can even snap it to a corner of a screen.

Seems on Plasma 6, it can sometimes happen where the window will snap out of bounds.

I made a video of the bug: https://youtu.be/TP_Wisn1DLw

My setup is a dual monitor setup, and the video is taken from the right monitor (If it matters, that screen is NOT the primary screen, as set in KDE's Settings Manager. It does have HDR enabled too.)

You'll see in the video that it ends abruptly after I minimized the window. At that point, kwin_wayland crashed, but it seems to have been in a response to something happening in the kernel, strangely. I attached part of the system logs to this bug.

Here's what I got installed:
