Hi Sjoerd, sorry for having failed to follow up on this. I didn't check whether this bug report had new messages. Diederik has kindly pinged me that your message still needs a response. Thank you, Diederik!
I've put Lukas F. Hartmann as the CEO of MNT Research in CC.

I built a kernel without 32x8 AFBC disabled and am now back with a machine where I observe the regular flicker effect. I attached the contents of /sys/kernel/debug/dri/ff900000.vpu/framebuffer to this mail. I've also attached the output of `drm_info /dev/dri/card0`. > It would also be helpful if you could mention the display stack you're using > (e.g. which compositor).

Thanks! cheers, josch
