After working in Lightroom 5 and photoshop cc for an extended period (6 hrs or so) I lose my brushes especially consistently in the liquify filter. Then, the whole photo has a red overlay as if a mesh-- and then after I close liquify window my image is just a black screen. The only solution is to reboot. Any idea why? At first I was having issues with Firefox open but even after closing, I had same problem. I've updated all software and have 8GB of RAM with only those 2 apps open. Help?
Does turning off »Use Graphics Processor« in the Performance Preferences and restarting Photoshop have any bearing on the issue?
Could you please post a screenshot to illustrate the issue?
