In Photoshop CC 2014 rubber stamp tool not working propertly. My configuration; Win7 64bit / NVidia GForce GT360. I updated driver to newest version. No reason. In Internet newsgroups I found out that this problem has many people. Thus, this is definitely a problem with the new Photoshop (in some configurations, of course). Rubber stamp not responding properly. Quick-clicking does not clone the image. There also helps to turn off graphics acceleration.
