Public bug reported: Hi, I have a Laptop with a Ryzen 5500U, running Linux Mint 20.3. To make use of the graphics driver, I update the kernel from 5.4 to 5.13. The computer is booting up, the LM splash screen apprears and then the screen gets funky with a random assignment of pixels. It seems each pixel gets a random assigned color (white, red, blue, green?, black). The pixels change color roughly every 200-500 ms. This happens with 5.13.0-28 and 5.13.0-23. The laptop is not responding to anything.
Using 5.11.22 works without any flaws. AMD gpu drivers are installed correctly.
