Package: firmware-amd-graphics
Version: 20260622-1
Severity: important

Dear Maintainer,

I have a laptop equipped with an AMD Ryzen 5 3500U using integrated graphics.
After installing the latest kernel from Testing (7.1.7+deb14-amd64) I noticed a
problem while using it.
At first it was minor glitches of about 5% of the screen being replaced with
random blocky colours for just long enough to be noticed but would disappear
before it impacted anything.

Recently it spiked to 75% of the screen with multiple flashes in short
succession. I checked btop and it reported high CPU usage but low load average.
So it seems as though a lack of available CPU impacts this bug.

I would normally figure out this problem myself but I couldn't find any helpful
information besides bug #1093084.

Under normal conditions my screen doesn't have this issue, and I haven't
touched the internal cable connecting to the monitor.


For more information here is the setup I have:

Laptop Brand- Lenovo
Model- ThinkPad E595
Integrated GPU (According to lspci)- VGA compatible controller: Advanced Micro
Devices, Inc. [AMD/ATI] Picasso/Raven 2 [Radeon Vega Series / Radeon Vega
Mobile Series] (rev c2)

Information I got during the latest episode:
Reported load average- ~4-5 (CPU runs on 8 threads total)
Reported CPU usage- 100%
Memory usage- 47%
Swap usage- 39%
VRAM usage- ~48% (2GB is allocated for use)


I hope this is helpful. Thank you for all of the work you do!
