Intel Iris XE Problems with 4k 144hz and Display Port dsc

[Prelator]

Hello there,

i have a problem with my new laptop (Lenovo X1 Carbon G10) and my LG Ultragear 4k 144Hz Displays:

if i use the display with 144hz i get many problems and black outs / flickering on it.
i have always testet this:

when i use the display with 95hz i dont have any issue. I think this is maybe a Problem with non enabled Display Stream Compression (DSC).

have anyone an idea?

PS:

On Windows 11 i dont have any issues with this configuration @144hz.

best regards
