Graphical artifacts on GNOME Wayland, Linux 6.10.3, and EVDI >= 1.14.2

• Are you using the latest driver? Yes
• Are you using the latest EVDI version? Yes
• If you are using a DisplayLink device, have you checked 'troubleshooting'
  on DisplayLink's website? Yes
• Is this issue related to evdi/kernel? It seems so

• Linux distribution and its version - NixOS Unstable
• Linux kernel version - 6.10.3
• Xorg version (if used)
• Desktop environment in use - GNOME Wayland

I'm experiencing significant graphical artifacts when using GNOME on Wayland with EVDI 1.14.3 (and next versions). These artifacts make the system almost unusable, particularly when interacting with certain applications and desktop elements (try moving windows around if you can reproduce).

Summary:

• Docking Station: DELL D3100 DisplayLink
• Operating System: NixOS Unstable, Linux Kernel 6.10.3 (with 6.9.12 and EVDI 1.14.2 is working fine)
• Desktop Environment: GNOME (Wayland)
• EVDI Version: >=1.14.3 (rollback to 1.14.2 resolves the issue, tried 1.14.3, 1.14.4, 1.14.5 and 1.14.6)

Hi there! I ran git bisect and found the culprit: 3323f31.

In fact, building EVDI 1.14.6 again with the changes above reverted works perfectly.

Thank you, you saved my day. I had the same issues, reverting the commit solves it. The 1.14.6 is not very stable for me though, after random 2-3 hours the external monitor stops refreshing and "freezes".

Hi @archer-65
What machine (CPU and GPU's) do you have?
Please also attach dmesg logs.

Hi!

CPU: Intel i7-1255U
GPU: Iris Xe

I'll attach the dmesg logs next week, as I currently don't have access to the machine.
