Accidental palm touches have gone from 5-6 out of 10, to 1 out of 10. A significant improvement.

Is it possible to check the "velocity" of the canvas' position/rotation/zoom by comparing the values from one frame to the next and limit it to a natural speed(or perhaps freeze it in place)? I've had the canvas spin a whole 180 degrees and zoom in 1000% in what felt like 1-2 frames.

This would be great for the occasions the canvas "spazzes out", even if they happen less often now.

Selections in Pencil Only mode - we will fix that asap.

Closing selection - we will consider that improvement in the future.


There is significant improvement. Still there are some occasional touches, but less then before. I’d say its good now.

The only problem is with selections.

We have four types of it:
1. Lasso
2. Poligon lasso
3. Rect
4. Circle

I have only pencil mode. Only lasso tool uses only pencil to select (not fingers). All three other selection methods register palm touches which ruins work process and you need to waste time to undo. I think all selection methods should use ONLY pencil if “only pencil mode” is chosen.

Also, selection needs one more tweak. When you close selection with first point tap and try to undo this action, app deselect whole selection, not revert back only last step.

Tweaking these things above will improve work with selections in Artstudio.

Velocity - if you mean animation smoothness (framerate), canvas rotation should not make a problem.
Send more details so we can reproduce that. Video (with Preferences > Interface > Visualize Touches turned on) will be welcome
