Thanks for the update.
I'm going to give my feedback on painting in the new update as it's the only thing I've tested as of yet.
Painting with my tablet is MUCH more responsive now. Before this update the cursor would lag way behind when making quick strokes. The latency now seems on par with Photoshop.
Pressure sensitivity is MUCH better now, there is a nice flow between line thickness when changing pressure as you draw. However, I can only seem to get line thickness working with pressure. I can't get any fade at all. Not sure if this is down to the app or if there's a setting for it.
The jitter for brush strokes seems to be gone, just the aliasing letting it down atm. EDIT: On closer inspection there seems to be a lot of interpolation creating straight edges when drawing a circle or curved line quickly.
Brush strokes still have a lot of aliasing which looks better when zooming the canvas out. I guess this is a rendering problem and not to do with the lines produced by the brush. EDIT: I'm wrong. If i save the image and open it anywhere else, the aliasing is still there.
Cheers!
