To thank you for the enormous developments you continue to bring, I have made a "valgrind" that I hope will be useful. I've played a little with masks, with Gradient and with Sketcher. In the latter I caused the freeze with the color picker and then I came out with CTRL+C causing the creation of a dump. I used as settings in Preferences: Vdpau and OpenGL.
