Lags while drawing long curves



since latest release there are bad lags while drawing long lines in free hand mode on my surface pro.

All curves become edgy. This happens if i try to draw a curve that is longer than half of the canvas size and/or goes more than 90 degrees. Catchbook suddenly misses some pen imput and jumps from point to point.

I have no pen problems in other drawing applications like Photoshop, Illustrator or Autodesk Scetchbook.


Kind regards



Re: Lags while drawing long curves

@BPD - Sorry to hear you are having some issues with the new version.  We are investigating a similar problem.


Can you confirm your Catchbook Version (open a page > tap the "..." button > tap the "i" button > select the "About" tab)?

Also, which Surface Pro do you have?

Does the problem improve if you close and restart Catchbook?


Regards, Tom

Hi Tom,


Catchbook Version: 1.3.10491
Surface Pro 3 with Win 10 Aniversary


It doesn’t improve by restarting App or Surface. It still stays the same.


Kind regards.
