Linux Mint 22 Cinnamon - Artifacts

[miklinux]

Hi everyone!
I'm experiencing a weird issue with a Lenovo ThinkPad P14s G5 (Intel Arc + Nvidia) running Linux Mint 22 Cinnamon and connected to a Display link USB-C / Thunderbolt docking station: when working on the external monitors connected to the dock I often see small horizontal artifacts which suddenly disappear (will try to make a video at some stage), so the issue is purely aesthetical.

This happens only when I'm using the intel GPU as the primary device, while it works perfectly when I switch to the Nvidia card.

I would rather use the Intel card since it'll be better when running on battery and I don't have to remember to switch each time.

I'm using the latest version of the DisplayLink driver available in the synaptics repository (6.1).

Is this a known issue?

Thanks!
