[Solved] Slow moving of files

So I copied one drive to another in order to reformat.
Now I’m moving files back to the original drive.

What’s going on is it seems a great deal slow in doing this.
I just happened to grab the mouse at some point, and rolled the scroll wheel and about 20 files move.
I scroll it a few times and 100 files go by.

I did reinstall Plasma and it seemed to help somewhat, but didn’t totally fix it.
Idk if this a weird buffer issue or what, but has anyone seen this behavior before and know how to fix it?

An update came through today GREATLY speeding things up, but still seems wonky, but calling it solved.
Edit:
Site won’t let me edit original post topic though.
I should mention I saw kwin in the update if it helps.
