As per the above video, I'm getting some extreme flickering on my R9 290. This happens mostly on the desktop, but also to a lesser extend in web browsers (And not at all in games). Moving the mouse causes the issue mostly, though only on the main monitor, but even just opening the start menu with my keyboard causes it, though to a far lesser extent. It's a Powercolor 4Gb 290, stock clocks and never attempted overclocking.
I've got an Asus Freesync monitor on the left running 2560x1440 and a HannsG running 1920x1200 on the right. As you can see, only the main freesync monitor has the issue, it's had it for a while but over the last couple of days it's gotten far worse. Anyone know anything about this issue and if there's anything I can do to fix it? I'm running 16.9.1, though just got a popup that 16.9.2 is available so I'm going to try that, though since it's such a long standing issue, I don't hold much hope.
