No, this does no do anything, the bug is still present.

This may be related to stutter mode rather than gfxoff. If so, there is a fix in the pipeline for that. Does setting appending amdgpu.ppfeaturemask=0xfffdbfff on the kernel command line fix it?

Hello,
I have today compiled the drm-next kernel from (1) and find out the screen is
flickering and shows various artifacts. By bissecting I found the cause
is commit 005440066f929ba0dca8f4e0aebfbf8daac592cc. By reverting it the
problem went out.
I does not have idea about what to do next. Sorry if this should be posted to
some bugzilla instead, I have got a bit lost. If so, would You please
point my out what to do?
With best regards,
Pinkava J.
