Green screen in Loupe view/Full screen never loads

[keepof4worlds]

After a while working in LRc, photos do not display in Loupe view - just a blank green screen.  If I press f for full screen, the prgram just lits with "Loading..." on the screen, butI can switch back out of it. Evefrything else is working (grid view, histo etc). If I quit the program and restart all is well again...

First, try disabling GPU in the preferences (Preformance tab). Any better?
If not, recalibrate and build a new ICC display profile, the old one might be corrupted.
If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.

Will have a go, but it's also happening on my MacBook Pro, so GPU seems unlikely.  Will try the ICC profile route also, thanks

...Also I just see 11.01 is out so will try that first

Seems to be happening far less in 11.01: suspect an early version clitch which has been cleared up
