Since I have installed windows 10 I have a really annoying bug with photoshop wich is; at every action the interface goes to normal to lighter then go back to normal then lighter again etc. ( I have the lastest version of photoshop CC )
Sorry i didn't saw your answer sooner, my version is the very last one ( i don't know were to look to see precisly wich one is it ). The problem is solved though, it was caused by my dual screen instalation, i switched to just one monitor and it stop flickering. thanks
