I have found that Lightroom sporadically freezes in full screen. (F key) This happens more often with tiff files. and it has happened on both my 6 month old top of the line MacBook Pro and my client's older MacBook Pro.The only way out is a forced quit.
Same issue and happens often after editing picture then going to full screen. Sorry as no answer and also searching to see if any resolutions. Tempted to re import and use LR5 again
new to lightroom ...I have the same problem as above on lightroom cc ....does anyone have an answer about this ...thanks
Please follow the below steps.
Go to Lightroom Preferences from the Edit menu
Click on Performance tab
Uncheck the Graphics Processor
Let us know if that helps.
