12:52 tzimmermann: Venemo FYI https://gitlab.freedesktop.org/drm/amd/-/issues/4413
12:54 Venemo: tzimmermann: fingers crossed that it gets fixed. sounds really weird, I have never seen issues with DP on AMD GPUs
12:54 Venemo: tzimmermann: which GPU is this exactly?
12:57 tzimmermann: Venemo, this one https://www.techpowerup.com/gpu-specs/asus-rog-strix-rx-460-gaming.b3758
12:57 tzimmermann: i'll put the link into the report
12:57 Venemo: tzimmermann: do you use any kernel parameters?
12:59 tzimmermann: nothing special. i've added it to the bug report
13:05 tzimmermann: i suspect the monitor is not fully DP certified
13:21 Venemo: tzimmermann: just a random thought, have you tried it without DC?
13:22 tzimmermann: DC?
13:30 Venemo: tzimmermann: try booting with amdgpu.dc=0 on your kernel command line and see if it behaves differently
13:34 MrCooper: tzimmermann: amdgpu.dc=0 on the kernel command line, that gives you the old display code inherited from the radeon driver
13:35 tzimmermann: just tried. no change
14:05 Venemo: tzimmermann: does it work on windows?
14:05 tzimmermann: i'll try but it'll take a bit
