from 192k@protonmail.com
I can confirm this issue exists on rx560 i have discovered a workaround, if you copy the stock powerplaytable to a file with cat /sys/class/drm/card0/device/pp_table > pptable then load the stock pptable with sudo bash -c 'echo pptable > /sys/class/drm/card0/device/pp_table' the flickering goes away without having to lock the mclk to the highest state it may also be related to https://bugs.freedesktop.org/show_bug.cgi?id=110347 this bug. by default at boot the voltage for the highest pstate is the maximum allowable voltage(1150mv) not the powerplay defined voltage of 1025mv, all other pstates are not effected this is also corrected after reloading the pptable manually.
