Hi there,

Thank you for reporting the above, and for providing all the relevant information.

May I ask, is this still occurring for you? Was it only one particular PDF, or does it/did it happen with other PDFs?

Hi,

I am not able to reliably produce this bug. It hasn’t happened again since I first reported it. I will let you know if I can reproduce :slight_smile:

best,
Mussie
