PTPolylineEditTool causes jumping

We use PDFTron SDK for our ios swift project.
When polyline is created and then duplicated there is a problem that as soon as tool is changed PTPanTool, annotation jumps a little bit as can be seen in the video. I guess PTPolylineEditTool causes this problem but I cant figure it out how to solve that problem. I will be very appreciate if you help me.
Thank you already!

Hi @bilgehan,

Thank you for getting in touch with us about this.
We are able to reproduce this and are working on a fix.

I will keep you updated.

Hi @bilgehan,

We have made some improvements to the line annot handling which are available in a new experimental nightly build.
It’s available as a DMG download or via CocoaPods:

Are you able to test that and let us know if it improves things for you?

Hi @bilgehan,

We just released version 9.2.0 of our iOS SDK which includes the fix.
Our website will be updated next week but you should be able to update to the new version already.

Please let us know how it works for you.
