Bugzilla – Bug 1211558
Kernel 6.3 Ryzen 5600G amdgpu
Last modified: 2023-05-26 11:04:02 UTC
Created attachment 867129 [details] inxi (partial) kernel 6.3 running I have a dual monitor setup, running on a Gigabyte Aorus B550M MB running a AMD Ryzen 5600G amdgpu. The MB has 2 inputs for video, one HDMI and the other a Display Port. With the advent of the 6.3 kernel, the monitor attached to the HDMI port has developed a minor video distortion. Reverting to the 6.2 kernel removes the distortion. I have 4 other Tumbleweed setups, some running with HDMI video connections that have no problem with the 6.3 kernel. I'm assuming there is is a 5600G module missing or faulting with this machine. (Guessing really). * Both monitors are identical Acer X213H * When each monitor is used singularly, attached to the HDMI port, there is distortion. Not present with 6.2. * Attached singularly to the Display Port, no distortion. * Monitor attaches to Display Port using a HDMI cable with a Display Port Converter, that came with the MB. * Although I have distortion, I can still login and move windows to the non-distorted screen. (I've been using Tumbleweed setup for so long I can identify the distorted icons.) * Using Spectacle to make a screenshot, the distortion doesn't show up. I've used my phone to take shots for posting. * Computer also dual boots with Debian siduction. They released their first 6.3 kernel yesterday (6.3.3) and it is having the same problem.

Since the first 6.3 kernel came in, I've been searching through the logs, but didn't notice anything I could identify. Please let me know if I can attch more useful information.

So, I attached my HDMI female to DVI adapter to the end of the HDMI cable leading to the monitor presently showing graphics distortion, plugged the DVI plug into the monitor and the distortion disappeared. Mind you, I tried every combination of HDMI cables plugging them into every combination of MB inputs and this solved the problem. Spectacle showed no distortion in the screenshot, although the monitor was distorted ... somewhere in that anomaly is the answer. Both monitors and their HDMI inputs were fine with 6.2, one monitor needed DVI input with 6.3. I don't get it......but for now it's fixed. BTW - Sorry for comments 4 & 5, I saved as comment by mistake.
If you can reproduce the problem in some way and if it's a regression in 6.3, better to report to the upstream, e.g. gitlab.freedesktop.org issues. Otherwise we can close the bug for now.
Thanks Yes, I can reproduce it, and so, I'll see how well I can explain it upstream. And yes, closing it here makes sense.
OK. If/once you have a link to the upstream bug, please paste it here.
