"We have successfully compiled and deployed QPrintPreviewDialog in LTS Qt 6.5.3 for PDF preview from Windows or Linux OS to an Android target. However, we are currently experiencing some issues, such as some contents disappearing from the preview page when zooming in on the Linux compiled version and some lines appearing in the Windows compiled version when zooming in on the preview page."

Qt Support tested the attached example project and could not reproduce the issue on Android 12 phone but on Android 10 tablet the issue was reproduced. Please see the attachment.

Steps to reproduce:

Zoom near 200%(or more) and move the screen near the right corner for example. There will appear vertical lines and the text can distort.
