--- Comment #10 from Manga Tengu <mangate...@gmail.com> --- I found out what it was. And man, I deserve a golden achievement on krita-artists for such a sneaky bug report! When you open the brush editor popup, if you click on the main window, the popup will not close but go behind the main window, Becoming invisible. As long as this popup is opened in the background, you will notice the lag very clearly. I love myself *self-kiss* -- You are receiving this mail because: You are watching all bug changes.
