Horizontal artifacts when refreshing

cuyenboy · 08-23-2024, 10:47 AM

Hi,

i use a dock for many months with an acer computer on ubuntu 24 and all is working fine.
But I bought a new dell inspiron and i encoutered bad glitches when screens are refreshing.
Its a dual boot windows11 + ubuntu, and on windows without any driver, it works fine, no glitches. So, its not a hardware problem to my mind.
My other computer with the same version of ubuntu works great also it comes from the dell computer. But how to resolve this? Can you help me please?
As to me its a refresh probleme because when a drag the mouse it refresh the part of the screen.

Thank you so much.

I've tried to install intel graphics third party driver and wow, it was a disaster!
I've tried to install a legacy displaylink driver but same horizontal f... lines when i drag any window.
I've tried to install ubuntu 22 and....it works fine...

Any other idea to test on ubuntu 24??

I'm experiencing the same issue. Ubuntu 22.04, on a System76 Darter Pro, using the latest DisplayLink driver from the apt repo

Hardware CPU/GPU: AMD Ryzen 7950X + RX 6800XT (computationally, very capable setup)

Ubuntu 22.04 - no issues on DisplayLink 5.6 (I think it was the version installed)
Ubuntu 24.04 - DisplayLink 6.1, awful horizontal artefacts appear like when I had (in the past) very low performance graphics card installed

Artefacts are particularly visible when moving around browser window with a white page over non-white.

I remember such experience having those artefacts when had different, much less capable graphics card - Radeon Pro WX 2100

I have the same error.

I also have horizontal white artifacts.

Device: Lenovo ThinkPad L16 Gen 1
OS: Ubuntu 24.04.1 LTS
Docking Station: Lenovo Hybrid USB-C with USB-A Dock
Setup: two LG screens (model 24BP45SP) connected to the dock
Graphics: Intel® Graphics (MTL)

I tried both the repository and the direct download version of Displaylink. The file "DLSupportTool.sh" I could not find.
