So sorry to hear about these issues. Is the issue related to a specific document? If yes, could you please share the document with us?
This will help us replicating this issue at our end and help accordingly.
Thanks. I think the issue has been solved. I also sent a bug report through the app.
This is their response. I am posting it in case it will help other people.
This is a bug that I believed to be fixed in the new build (v1.3). It was the result of opening/editing a document that contains previously-locked layers.
Since I can see that you've updated the app, I have a couple of questions:
Does this drawing have locked layers?
Are you drawing with vector brushes?
Is this older documents, created prior to the update, that you're noticing this? If it is, or you're unsure, please try creating a new document and following these steps:
1. Create a vector layer. Draw a circle and lock the layer
2. Close and reopen.
3. Unlock the layer, draw a stroke on the right side of the canvas.
4. Relock layer.
5. Close and reopen
6. Is the circle distorted?
Please let me know if the drawing is still distorting so I can let the team know that the bug is not fixed.
This erratic behavior has happened to my illustration as well. Closed the app, opened it later only to find several layers had been rotated - and artwork that fell off of the canvas was deleted/cropped! Hours of work lost! So random and frustrating!
