Green artifacts for transcoded videos when using intel arc a380 vaapi

I get green artifacts in the transcoded videos when using hardware encoding on my intel a 380 gpu. A horizontal green line is shown and colors are way off with ghostly artifacts.

(I will self answer this as i searched hours to fix it and want to have the result posted here for others)

I resolved that issue by using QSV instead of VAAPI in the hardware transcoding settings of immich admin area.

Files needed to be reencoded ofcourse, browser cache emptied then i could see the result. File size also shrunk significantly.

Further i would recommend to use hardware decode for videos as well (yes comes with a warning of incompatibility) that sped up my transcoding significantly as well.
