The video is similar to what I am seeing, in the video it is more severe.

If the following commands are executable on your machine:
$ ls -d /sys/class/drm/card?
/sys/class/drm/card0 /sys/class/drm/card1
$ cat /sys/class/drm/card1/device/pp_dpm_sclk
0: 300Mhz *
1: 500Mhz
2: 698Mhz
3: 858Mhz
4: 899Mhz
5: 935Mhz
6: 969Mhz
7: 1000Mhz
then (question) does the flickering go away if you run:
$ echo 1234567 > /sys/class/drm/card1/device/pp_dpm_sclk</pre>
