--- Comment #6 from Mun, Gwan-gyeong <elongbug at gmail.com> ---
A sympton of weird screen seems that MSA uses wrong configuration.
The commit "drm/i915/dp: Add support of BT.2020 Colorimetry to DP MSA"  
 1) checks use case of BT.2020 and enables MSA for VSC SDP for BT.2020
Colorimetry.
 2) changes a calling of intel_ddi_set_pipe_settings() function into
intel_ddi_pre_enable_dp() to handle colorspace of drm_connector_state.

The changed MSA setting timing might lead (I am not sure) weird setting of MSA,
I am on digging it in detail.

Ken, could you share the kernel log which Lakshmi said.
