I'm fine. I found a solution that works for me.

The i915 gpu driver belongs to the kernel: linux-image-amd64.
I first saw the problem with version 5.10.70-1
(linux-image-5.10.0-9-amd64). Now I'm using version 5.10.84-1
(linux-image-5.10.0-10-amd64) which also works fine using the boot
parameter "intel_iommu=off". Although I did not try this version in the
default configuration without this boot parameter.
