(Note: I'm not 100% sure this should go in kwin, nor if it is in the right subcomponent of kwin. If I made a mistake, I apologize!) Seems that, in Plasma 6 (RC1), windows have a tendancy to 'snap' around 1/6th the way down the screen (See video). It seems to also snap a little below the task bar, but to be honest, that's very likely to be intended. Video: https://youtu.be/poZ5vH8vUZo
Thank you for your bug report and detailed video. This seems like intended behavior when you have center snap zone enabled. If you go to settings->window management->window behavior->movement, you should see settings for that. Feel free to reopen if your center snap zone is not set to None!
Correct, it is indeed set to "None". Also, I noticed something else that might help you pinpoint this issue. I got two monitors. This seems to only happen on the primary monitor. (But that might be intended.... if the feature was enabled that is) Sending a screenshot of the window behavior settings (Just in case)

It might be the case that something on the other monitor is causing this behavior, like panels. Are you on X11 or wayland? Also I haven't been able to reproduce on my end, so we would need to figure out what is causing this.

Sure thing, uploading now! We're on Wayland, Fedora 40 will be wayland only as well.
Created attachment 164986 [details] Both Screens The left Konsole window is currently snapped.
Oh by the way, this morning when I took a screenshot of the "Window Behavior Settings, I freshly logged into Plasma 6 and simply opened systemsettings and spectacle, and it did it.

There seems to be nothing that could be causing the window to snap, and I can't reproduce on my end. Do you observe any changes in the snapping you reported if you set center snap zone to a non-zero value? I am a little out of ideas for now. Would need to think about this a bit.

I went ahead and tried that. I've set the Center Snap Zone to 1px. On the left screen (The one affected), the behavior still occurs, but... as I move the window, it asks like if there's now 2 snap zones right on top of each other (As it snaps, if I move it a tiny bit, you can see the window snap to the following pixel a tiny bit). On the right screen, nothing snaps still.
