Certain emails black, have to calibrate display every time I wake from sleep
The color calibration does fix this issue, but the issue returns after sleep mode every time! I have to go to System Preferences>Display>Color each time. All I have to do is open the Color dialogue box and the issue is fixed. But it's every single time I return from a break and have put the computer to sleep, every day.
I'm running Mail 11.5 on High Sierra with an early 2011 MacBook Pro. Mirroring to Benq external display.
Ideas?
Thanks
