on-screen artifacts (red pixels) at high resolution with Intel HD 630 (Kaby Lake)

Hi,

I am experiencing on-screen artifacts (red dots) when running at
1920x1080 on HDMI out. I've ruled out a hardware (cable, TV or GPU)
issue by installing win10 which does not show those problems.

This is by using stretch, issue occurs with both kernel 4.9 or 4.13
available in the backports. The hardware is intel HD 630 (Kaby Lake).
Xorg uses the modeset driver.

I was wondering where to get help regarding whether this is a bug :
- xorg?
- kernel i915?
- kernel drm?
- other component?

Thanks,

Alex
