For several months I have had random shapes appear in my files when using vector masks. The scrambled imagery only appears at random and at certain zooms (over 25%) and will disappear upon restart of Photoshop. If I flatten the file, it will retain the scrambled imagery, but otherwise it seems to not actually corrupt the data, just the view on screen. Any ideas? I've been fighting this for months and have replaced drives, video cards, and it still persists.
So far so good.
Not so; if turning off »Use Graphics Processor« were to resolve the issue it could indicate that your GPU driver needs to be updated (or the reverse) and as long as it’s turned off you lose a bunch of functionality that dependes on it (the Rotate View Tool for example).
What are your OS and hardware specs?
Are Photoshop and OS fully updated?
What have you done in way of the usual trouble-shooting routines (trashing prefs, system maintenance, …) so far?
I'm running OS X 10.6.8 on a Mac Pro quad core. 2.4 GHz processor speed. 32 GB of memory. I have a ATI Radeon HD 5770 and Nvidia Ge force 8800 GT video cards and an Eizo CG243W.
The issue I believe has been present for about a year, I'm running CS6 which has been re-installed a couple times and is up to date. I generally only run PS, Chrome, Outlook, and iTunes. Although will end up with AI and Acrobat and sometimes InDesign on occasionally.
My machine has also been fully wiped and the OS re-installed. We've also swapped out my data drives. There is also often a scrambled patchwork on re-draw, while opening files in PS, or zooming in. My instinct says its a video card monitor PS thing but the video cards have also been swapped out with no difference.
