Hi, Yesterday came the 6.7-rc1 kernel. And surprisingly it turned out it is not working with my LG C3. I use this OLED TV as my primary monitor. After login to GNOME I see a horizontal flashing bar with a picture of the desktop background on white screen. Demonstration: https://youtu.be/7F76VfRkrVo I made a bisection. And bisect said that the first bad commit is: commit ed6e2782e9747508888f671e1101250bb19045be Author: Alvin Lee <alvin.lee2@xxxxxxx> Date: Mon Oct 23 14:33:16 2023 -0400 drm/amd/display: For cursor P-State allow for SubVP [Description] - Similar to FPO, SubVP should also force cursor P-State allow instead of relying on natural assertion - Implement code path to force and unforce cursor P-State allow for SubVP Reviewed-by: Samson Tam <samson.tam@xxxxxxx> Acked-by: Hersen Wu <hersenxs.wu@xxxxxxx> Signed-off-by: Alvin Lee <alvin.lee2@xxxxxxx> Tested-by: Daniel Wheeler <daniel.wheeler@xxxxxxx> Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> drivers/gpu/drm/amd/display/dc/hwss/dcn32/dcn32_hwseq.c | 17 ++--------------- 1 file changed, 2 insertions(+), 15 deletions(-) My hardware specs: https://linux-hardware.org/?probe=1c989dab38 -- Best Regards, Mike Gavrilov.
