SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: EndeavourOS 64-bit Kernel 5.9.14-arch-1 (available in About System) KDE Plasma Version: 5.20.4 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Running on Asus ROG Strix III, with Nvidia GTX1650.
After further experimentation, I can see this only occurs when the panel is top of screen or right of screen.
