Description

I recently bought a Sapphire Radeon RX 580 Nitro+ 4 GB GDDR5 and I'm using the amdgpu drivers on ArchLinux with xmonad.

Unfortunately the entire screen flashes randomly, usually correlated with clicking the mouse button in chrome. Enabling TearFree makes no difference, disabling the hardware cursor makes no difference.

I do not wish to use amdgpupro, for ethical reasons.

I can perform more diagnostics if needed, but I appreciate that this is a very difficult to reproduce problem so my hopes of a solution are low...
