From the day I've bought that card, i started to have some problems with flickering (mostly) and freezing. The worst thing is happening after switching from fullscreen (game) to desktop. (video example below).
None of updates resolved this problem
rx 5600 xt OC - OFF
I have also tried CRU program for freesync refresh rate, but it doesn't works.
Maybe you are also having this kind of problems, and you want to share some solutions 🙂
