This can easily be replicated when mousing over the wow icon at tastkbar (and get the little window showing the game real time), while having browser in foreground. Randomly parts of wow flashes through. Game runs fine, just getting some shadow flickering occasionally. Video of it: https: // streamable. com/iu5klu
the flickering issue at least is an nvidia driver issue, i believe from 460 and onwards. i am using 457.30 and it does not have the problem. whenever i’ve tried 460 and 461 the flickering has come back.
I do have freesync on main monitor, while 2nd monitor is just for browsing/watching streams (doesnt support freesync/gsync etc). Theres also a thread on US which i think describes same issue.
