brush glitching after switching from rubber
Ash
I haven't encountered this, but are you clicking the preset circles on your bar below the color wheel (or if you're just switching the same preset from a brush to a blender) or the presets below for how your blender behaves as far as shape is concerned? Because if you're clicking the one on the bottom, it's still going to be a blender brush.
(ALSO OUT OF CONTEXT BUT I SAW A DAZAI PFP AND SHALL COMMENT ON IT AND POSSIBLY STEAL IT.)
