@szimek
Tonight , I want to take signature_pad in my another project ( it must support "undo")...
I'm sure that , this following bug has always been there ( signature_pad v2.3.2 ). So I submit this issue .

The same bug , fromData and toData , the draw is not completely the same .
#270

Do you have the impression ?

Thanks very much for reply.
On this fixed version: (https://jsfiddle.net/szimek/h80phxyr/11/)
I see the problem again .
You can draw some curves (like six letters "jjJJjj") ,then click "undo" button six times .
On this online demo.: (https://jsfiddle.net/szimek/h80phxyr/11/)
I have a try ,maybe i don't understand ...
The picture compare.

Thanks for submitting it. I won't have time to look into it in the next 2-3 weeks, so it would be great if anyone could take a look at this issue and come up with a fix ;)

Hello,

I think your problem can be solved by setting following property:

throttle: false

http://jsfiddle.net/PieterVanPoyer/7q0hzzuy/

The throttle property makes the signature_pad more performant and smooth, but makes the undo action a little more unpredictable.
Defaults:

throttle: 16

I've created the fiddle with the throttle property to false. Please, try your testcase again.
I'd love to submit a fix for this issue later.
