Hello,
Just installed Debian 12 on my computer for my switch from Windows, was previously using it on a laptop and was happy with it so I stuck with it.
I installed KDE Plasma on Wayland, then switched from the Noveau drivers to the proprietary drivers precompiled in apt, however performance was lack luster, so I installed the drivers listed on NVIDIA’s website (ver 555). I uninstalled the drivers I installed with apt (sudo apt purge nvidia*), and installed the newer drivers in a tty with no NVIDIA software running or any GUI. The installation went smoothly with no errors.
Performance is now as expected but I am getting serious visual artifacting, and I can’t seem to find anyone else with this issue. All animations including typing are quite buggy. Video playback on YouTube is buggy and laggy, along with scrolling. Typing is buggy and randomly shows me pressing backspace before correcting itself to the correct text entered. The issues do not persist when starting KDE under X11.
Result of nvidia-smi:

Could anyone more experienced help me out?
