RFC because I'm not sure if this is the right approach.
Could you please file a gitlab issue for us so we can get someone from our display team to take a look and see if there's anything else that could be done
before we take the quirk route?

Thanks for the investigation and the quirk,
Rodrigo.

The flicker manifests ever few seconds 1-3 black frames in quick
succession.

On windows 300Hz can not be selected for the iGPU, but the panel advertises
it.

A cleaner solution would probably to go over the pixel clock, but for this device there is only one 300Hz mode in the panels edid and that is at the nativ resolution. Chroma subsampling was not tested as linux afaik offers
no way to easily enforce it for intel gpus.
