Hello, I am using amdgpu and mate on debian, but I have the very same
issue. The only way to fix it was to downgrade the Kernel to 5.3.0. I
already wrote to the amdgpu devs but got no response... My message was,
back then:
Hi, on my netbook (debian bullseye, AMD A4, Sea Islands), after
updating the kernel to version 5.4.6 and logging into mate desktop, my
screen looked like this (see attached picture).
If you look at the image, do you have any idea what is happening
there? To me it looks like the framebuffer data is misinterpreted at
some stage. The picture looks good on the lightdm login screen, it is
only corrupted when I start a user session and when I then switch to a
console (ctrl+1), the screen looks correct for a second before it
switches. When I switch back (ctrl+7), it looks correct for a second
and afterwards, it turns corrupted again. I was looking into these
commits a bit but I don't have any idea... Maybe mate/marco is doing
something it shouldn't but then, much more people would have problems
now...
I took a screenshot but on that, everything looked fine, that is why I
took a picture. I assume it came by one of these commits, since these
were the only amdgpu changes between a working and a non-working
kernel:

drm/amdgpu: add invalidate semaphore limit for SRIOV and picasso in
gmc9

drm/amdgpu: avoid using invalidate semaphore for picasso
commit 413fc385a594ea6eb08843be33939057ddfdae76 upstream.
It may cause timeout waiting for sem acquire in VM flush when using
invalidate semaphore for picasso. So it needs to avoid using invalidate
semaphore for piasso.

commit 210b3b3c7563df391bd81d49c51af303b928de4a upstream.
This patch fixes 2nd baco reset failure with gfxoff enabled on
navi1x.
clear state buffer (resides in vram) is corrupted after 1st baco reset,
upon gfxoff exit, CPF gets garbage header in CSIB and hangs.

drm/amdgpu: invalidate mmhub semaphore workaround in gmc9/gmc10
commit f920d1bb9c4e77efb08c41d70b6d442f46fd8902 upstream.
It may lose gpuvm invalidate acknowldege state across power-gating off
cycle. To avoid this issue in gmc9/gmc10 invalidation, add semaphore acquire
before invalidation and semaphore release after invalidation.
After adding semaphore acquire before invalidation, the semaphore
register become read-only if another process try to acquire semaphore.
Then it will not be able to release this semaphore. Then it may cause
deadlock problem. If this deadlock problem happens, it needs a semaphore
firmware fix.

drm/amdgpu: initialize vm_inv_eng0_sem for gfxhub and mmhub
commit 6c2c8972374ac5c35078d36d7559f64c368f7b33 upstream.
SW must acquire/release one of the vm_invalidate_eng*_sem around the
invalidation req/ack. Through this way,it can avoid losing invalidate
acknowledge state across power-gating off cycle.
To use vm_invalidate_eng*_sem, it needs to initialize
vm_invalidate_eng*_sem firstly.
