it would help if you posted a sample of the image along with greater detail: show the Layers and Channels panels, describe the filter used, your version of PS and any additional information that might be helpful if we tried to replicate the effect. To post the Image, click here:
Meanwhile, choose Preferences and in Performance, uncheck Use Graphics Processor and restart Photoshop. Let us know if that solves the problem.
Hi, thanks for getting back to me.
I tried the graphic process and the problem still persists. It's not just on the screen, its actually on the layers, as if a white shape had been pasted over multiple layers.
Pasting a partial screenshot here, as it is design work i cant currently share online, but can provide more if i need to.
But this image gives you an idea of whats going on:
Using photoshop CC 2015
Do you mean the white lines from the Grid overlay you show in your screen shot.
Simply turn the Grid off.
I'm afraid it's not quite as simple, that 'grid' is an artefact that has suddenly appeared on almost all my layers.
I haven't simply turned on a grid. Have you ever seen this error before?
Or am i missing something?
Even undoing as far as i can, saving a new file and opening on another computer is still showing it, and it's very frustrating.
Is View > Show > Grid checked?
If so, choose Preferences > Guides/Grid and Slices... what are the settings?
im away from the office now, but its not guides. They have apeared on most-but not all- layers, as if pasted there, and can be deleted separately for example, but undo doesnt get rid of them?
I will try and update with more info in the morning if anyone has seen this happen before
I can confirm its definately not a grid, and is a physical element ‘drawn’ across multiple layers, that wasnt there before. But now when i undo it was as if its always been there. Any further info i can provide to find a solution, or even a cause?
I am not sure but there is one layer in layers panel named pebble-front.. (its layer mask have white line like the one overlying in picture) check that layers once.
hi, thanks again. Theres actually a few layers showing it like that, all of which have had this grid appear, but layer maskes seem they could be a contributing factor, perhaps i had too many open masks running and the file just corrupted?
