I use photoshop to make digital art, something keeps happening where these multicoloured pixels appear over my sketches and I have no idea why, what it means or how to stop it from happening. They disappear if I brush over them but I'd like to stop it from happening in the first place. I have only used the brush tool on this layer and there are two other layers, the background layer (unaltered) and a layer with some colour fill around the drawing (not where the pixels appear.
Has anyone else experienced this? I've asked around but nobody seems to have even encountered this issue let alone know why it's happening or how to fix it. Thanks.
We're sorry about the trouble with Photoshop. This is certainly very strange behavior. Would you mind telling us which version of Photoshop are you using along with your computers operating system?
If you zoom in & zoom out on the document or if you hide & then unhide the layer on which you are drawing, do the colors disappear? If yes, then please try disabling the option to Use Graphics Processor from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.
