I know this subject has cropped up numerous times, but I just though it would be interesting to find that the blender-2.78.0-git.a372638-windows64 I downloaded has the horribly slow texture painting performance, whereas the regular 2.78c I downloaded is fine.
I know bugs etc are to be expected in the experimental/daily builds, but even so I thought it was worth mentioning. I’m wondering if there’s a setting somewhere, or whether there’s something different in the build…
