Well I'm stumped then. Sorry.

Thank you for the suggestion!

Disabling the compositor did improve the situation.

But there is still the same issue as with the Intel driver: dots appearing on 3d objects. (See screenshots of the book animation below)

Installing a newer kernel from stable-backports did not change anything.

I would try switching the compositor off. They can cause all sorts of weird issues.

Otherwise try the newer linux-image-amd64 package from the beowulf-backports repository.

Compositor, perhaps? Which desktop is this?

Thank you for the fast reply!

With AccelMethod UXA and GLAMOR I get the same artifacts as with SNA: dots appearing on rendered 3d objects.

Try

  Option "AccelMethod" "uxa"

But if GL rendering stimulates the problem the DDX driver is probably not involved. EDIT: no, wait, only Firefox v103 or newer will use hardware acceleration for that device.

Haswell CPUs need the intel-microcode package to avoid instability but I don't think that's relevant here.

T430/T530 Intel HD integrated graphics artifacts

Hello,

I have graphic artifacts on ThinkPad T430 and T530 with integrated Intel HD 4000 GPU. Sometimes white dots appear all over the screen.

The artifacts appear more often, when there is intense rendering, for example on https://webglsamples.org/ .

The hardware was tested extensively (memtest) and looks alright. It seems to be an xorg driver issue.

I tried using the intel driver instead of the modesetting driver by creating the file /etc/X11/xorg.conf.d/20-intel.conf:

Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
EndSection

Now artifacts only appear on objects, but not on backgrounds.

How can I fix this problem?

Thank you in advance for any help!
