Video quality deteriorates after locking account on Arch Linux with KDE Plasma using AUR

[sprow-dev]

I have a weird issue where loacking my account, it opens a bunch of hidden windows under that X11 task manager (taskbar) icon issue mentioned previously (on both AUR and flatpak), and then the video becomes a laggy mess and has some kind of compression artifacts or something. This issue is only confirmed on the AUR version, however, I have found no difference between the AUR and Flatpak versions.

I am not using GNOME because I hate GNOME and much prefer KDE Plasma. Linux Kernel 6.13.6-arch1-1, KDE Plasma 6.3.2, Qt version 6.8.2, and Wayland.
