I was having the same problem since last week.
This helped me. Go to
Preferences/Performance and uncheck Use graphics processor.
Hope this helps.
Yes, thanks, this works - but at the expense of smooth zooming, etc, when working on images. It's like stepping back into the distant past. I've tried the various sub-options under that one too, and none make any difference.
We're up to the third release of CC 2018 here at the time of writing, with no fix in sight. Crazy.
I dont have that problem in my i5. But in both my i7s, its the same. I wonder why.
What CPU do you run??
That's interesting! Both of mine are Ivy Bridge i7's. One is an HP laptop and the other a desktop machine I built myself based on a Gigabyte motherboard. Both run the built-in Intel HD Graphics 4000 only.
It's a pity my backup i5 desktop rig died recently. It used nVidia graphics too, so I'll bet it wouldn't have suffered from the same problem.
Beats me why it would come down to i5 vs. i7. Maybe in your case it's more to do with a generational gap between processors, which would mean different graphics specs. Or maybe the i5 happens to run discrete graphics whereas the i7 doesn't. If your i7 is an Ivy Bridge, we might be looking at a glitch with HD 4000 graphics as the true culprit.
Both i5 and i7s are Ivy Bridge with IGPU. I use 6th gen i3 in my workplace without discrete GPU and its smooth over there.
I edit over 100 photographs for ads. And the problem is really slowing me down. And I cant get a hold of any decent GPU because of the shortage.
OK, so much for that theory...
Can't you downgrade to CC 2017? Or pick up a GPU that isn't 'decent' enough for crypto mining just to use temporarily? You don't need much grunt for photo editing.
Just bought a used 980Ti today. I guess I will okay for 1 year now.
Eureka! I just noticed the problem has gone away after updating to the latest version of Avast antivirus. Avast was clearly the culprit in my case, on both computers. It was also causing other problems on the laptop manifesting as high CPU usage - most notably in Filemaker Pro Advanced.
Hope this provides a lead for anybody else suffering similar problems. Update Avast, or suspect other antivirus programs.
