Desktop bricked/glitched on fresh install?

[Wobbelblob]

Hey, so I wanted to try Kubuntu, but I ran into the following problem: Already on starting from my USB stick, I was greeted with the fact that on the mainscreen, only the bottom 10% where shown. That was fixed after I got into the safe boot option to install it, which was fine. But after installing and booting it, same thing happens. From the main screen, only the bottom ~10% with the task bar are visible. The mouse is not visible if I got into the black area, but everything apparently works. Second screen is fine. Considering that the safe boot fixed it during installing, I assume it is a problem with my Nvidia-card? Any advises on how to fix that?

Kubuntu version: Kubuntu 25.10 Plasma 6, current download from Kubuntu.org
Graphics: Nvidia 2080TI
Other OS? Yes, I have an installation of Bazzite OS, Zorin OS and Windows. Zorin mostly because I am too lazy to delete it.

Anything else needed?
