Bug freehand annotation builds up huge latency

[anon9832]

When annotating PDFs, I have noticed that latency is often larger than in other editors (e.g., Xodo) and this can get much, much worse as one adds more annotations. A workaround is closing the document and reopening (but, of course, this is not a good workaround). (This is happening to me on Android 12, Samsung tablet, using S-Pen).

Thanks for your reply, and apologies for the delay. Here are the answers:

1. Did you set "Pen" or "Brush" for "pencil" property: Pencil.
2. Did this issue happen to all PDF files or just some large PDF files? It can happen on files that are less than 2 MB. But this is erratic: it can happen, and then stop happening, and then maybe start happening again.
3. I have just seen the same problem with Foxit PDF Editor for Android, version 12.0.0.0627.1538. Again, as I say, the behavior is not always present: it can appear and then disappear in that same file.
