Probably NVIDIA related

I tried to reproduce this issue by entering the overview with the default keybind Meta+W and moving the cursor around to the various window tiles. The issue doesn't happen on my machine. Here's my system information:

Operating System: Manjaro Linux 
KDE Plasma Version: 6.2.2

This is happening on my system, too (it also affects the Desktop Grid, since that's part of the Overview now). My system has an RTX 4090, so since Alex couldn't recreate it with his AMD graphics card, I'd concur with Nate that it's likely to be NVIDIA-specific.
