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=20
2: 698Mhz=20
3: 858Mhz=20
4: 899Mhz=20
5: 935Mhz=20
6: 969Mhz=20
7: 1000Mhz
then (question) does the flickering go away if you run:
$ echo 1234567 > /sys/class/drm/card1/device/pp_dpm_sclk
