Usage of such brushes is "at your own risk" :) To make sure my test was well performed, I double checked again. And this is my experience on Windows : 1) Hovering doesn't stutter anymore however selecting this fuzzy brush leads to considerable frame drops even just with hovering. 2) When I use my mouse to paint, the cursor doesn't freeze on the canvas, but the frame drop is even more noticeable as it increases while painting; 3) When I use my pen to paint, the cursor will freeze, the stroke will not render in real time even if it's slow, and I must wait about 3 s after I release my pen before I can see the cursor moving again and the stroke rendered on the canvas. 4) I confirm that using shift+drag is smooth, but the framerate drop of the GUI seems abnormal. So yeah. The gui's frame rate drops severly as if what is happening on the canvas is somewhat linked to GUI. Sound like a rendering issue overall. -- You are receiving this mail because: You are watching all bug changes.
