Photoshop shows as solid red screen

Does anyboy else have issues with photoshop looking like this in 'normal' screen mode on a MacBookPro? 'Full' screen mode is fine and also fine on my attached monitor.

Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue? 

Does turning on »Deactivate Native Canvas« (Photoshop > Preferences > Technology Previews) and restarting Photoshop have any bearing on the issue?

Hi

Try enabling this option in preferences and restarting Photoshop to see if it helps

Thank you both. It seems to have temporarily/permanently righted itself, and I was waiting to see if it returns: if it does, I'll give both options again. Thanks for your thoughts -
