Photoshop CS6 on a late-2012 iMac with 32 gigs RAM. Since updating to Yosemite 10.10.4, painting on a mask has become very slow. For example, if I paint and then try to switch the brush from black to white, or vice versa, the pallete colors won't swap; nothing happens for a long time. I've found that clicking on the mask makes the application responsive again. It's as if the thumbnail is not updating until I click on it, and until it updatres I can't do anything.

This is a new behavior since updating from 10.9.5 to 10.10.4. Does anyone else experience this and/or have a fix?

Have you installed the WhiteWindowWorkaround plugin for Photoshop CS6?
