"gtk theme change" from kde5 appearance settings breaks driver physical rendering on gnome-terminal window/kde system monitor
Hello
First of all, I choose Wayland whenever possible on my machines. The second is, I had to take iphone photos/videos of screen glitches since built in tools record/image a screen in perfect shape while it is completely distorted in RL. It is almost like a physical cable got broken.
Under current openSUSE Tumbleweed (20231210) kernel and "vanilla" kernel which is said to have zero modifications I have this strange problem that modifying the "gtk application theme" causes a major display issue on gnome-terminal (gtk3) and kde system monitor. They display animated pixels in any kind of action such as cursor blinking and gnome-terminal actually displays completely transparent/ corrupts screen sections when moved.
As I own 2 different systems having openSUSE Tumbleweed, the i5/hd5500 which also have FOSS drivers showed the same glitch.
It is a very low possibility but in case of file corruption I added a fresh new user to the system. I launch gnome-terminal first time, there isn't any issue. I change gtk theme to another built-in, it still works fine. When I logout and select gnome-session from gdm everything is fine however gnome-terminal is horribly corrupt.
I also installed a fedora39 to user via distrobox. I updated everything and installed gnome-terminal to that distribution. The idea is to isolate any packaging differences. Gnome Terminal of Fedora 39 from that same users home is corrupt too.

Adding this screenshot from SDDM/KDE which lately became unusable (I switched to GDM) in case it is related.
SDDM issue was a very rare happening until Kernel 6.5.x+ . It became gradually worse. As I don't really use gnome-terminal, I can't pinpoint when this issue started to appear.
I can test/try things as directed. It includes installing another distribution or letting OBS build kernel. (can evict 40GB mint/ubuntu 20 temporarily)
