Address the claims to AMD driver team bugmakers. It is design flaw of their driver and BIOS, overclocking via CCC results in the same problems. Beyond of my understanding why AMD software team NEVER think before designing some technology, beyond of my understanding why NVIDIA can think about possible display sync issues and disable ultra low dynamic downclocking in dual-display systems whilst AMD always put tones of such issues and headache on users/third party software developers etc. So spam AMD to make it fixed, honestly I'm deadly tired of doing AMD job and providing endless workarounds for their drivers. I'd better focus on new functionality rather than on covering AMD's back, sorry.
