odd problems with HEVC encoding in video on AMD GPU
you're experiencing an unusual problem with your RX 570. when editing in video editors like premier pro or camtasia, scrolling through the timeline causes a grey screen in both. after installing the hevc codec, the issue persisted only in camtasia, where it would display a black screen followed by a rapid switch to normal video previews. converting the video to h264 resolved the problem, indicating the issue isn't related to your graphics card. you mentioned not having adrenaline software installed, only drivers, and performed a clean driver update via ddu.
