Thanks @acelankao <3 I can confirm the issue is fixed when upgrading to `sudo apt install linux-oem-24.04` (upgrades to `6.8.0-1011-oem` in my case).
I had the same issue with a fresh Ubuntu 24.04 (kernel 6.8.0-41-generic) and a completely new Dell XPS 13 9340 with the non-touch internal display. External monitors are no problem. The horizontal lines only appear when moving the mouse.
