Is anyone looking into this or are you expecting us to switch over to -pro with dal/dc asap? I have the exact same problem with both radeon and amdgpu. I don't know if this problem has always existed, it did since I remember. 144 Hz is unusable, so I always went back to 120 Hz. It works with the Intel iGPU on the exact same monitor, I also checked edid and modelines. It has always worked on windows.
