I first encountered kernel 6.3 with openSUSE around May 5th. My dual monitor setup developed graphics distortion with the   monitor attached to the HDMI port, the second monitor, attached to the Display port had no distortion. Partial inxi follows:

This is the body of the Bugzilla I filed with openSUSE. With the siduction kernel, it would read the same.: 


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.


This is the link to the openSUSE Bugzilla entry, I couldn't get attachments to work in this post.

Am I guessing correctly about a missing or defective kernel module for the Ryzen 5600G? 

If I can post any other useful information, please let me know.

TIA

For myself, 6.3.3-1 stops loading, doesn't get on to the graphics part. I removed it and things work again so it seems tied to the kernel rather than anything else.

There are no problems at the moment.

Thanks for the response, I've reverted to the last 6.2 kernel also.   
I've also heard mention of the no GUI when using 6.3, but I don't remember what hardware they're using.  

@edlin
Your setup is interesting, difference being your ASUS MB mine is Gigabyte. Since I've seemed to have tried everything else, I might see if I can find a HDMI to DVI cable and see if that makes a difference.

I was waiting for the siduction 6.3 kernel to compare it to the openSUSE kernel. I'm still thinking there is something in the kernel that doesn't like the 5600G/Gigabyte combo. It wouldn't be the first time that has happened.

Thanks for the responses, gonna investigate some more.

The differences between Gigabyte and Asus should be small in terms of the problem, as the CPU and chipset are identical.
The cable: It is a cheap cable from Amazon Basics. I needed it because my EIZO monitor has no HDMI input.

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.

Thanks for your response.
