Description

Hello. On occasion the colours of my screen get inverted/washed out after a i unblank the screen. It usually fixes itself after a few blank/unblank cycles.

I am running Arch (latest kernel drivers etc) on a Radeon 6850 GPU connected to the monitor using display port (in case it matters). Using open drivers and wayland with Enlightenment as desktop env. Checked with the E guys and it most likely its not on their side.

Any more info i can provide? I don't see anything weird in the logs when this happens.
