https://www.phoronix.com/scan.php?page=news_item&px=AMD-V4-Adaptive-VRR- FreeSync Is this maybe related?
This would be unrelated - those patches are still in review and not part of any tree yet.
Luminance flickering is also a bit different from typical flickering. It is a more subtle effect and doesn't have any sort of visual corruption associated with it - lines, the screen displaying black, etc.
