Hello @clearluvmoki ,

To investigate further, please provide the following:

  1. It looks like you tried to attached the sample PDF you used, but I’m unable to open/download it. Could you re-provide this file?
  2. We’ve made some fixes to our text selection since 10.5. Are you able to reproduce the issue on our latest release (10.9)?
  3. Are you also able to reproduce this issue on our electron sample? You can find it here: GitHub - PDFTron/webviewer-electron-sample: Sample to demonstrate integrating WebViewer into an Electron App
  4. The WebViewer constructor, with all options defined.

Hello @clearluvmoki ,

I was able to download the PDF you provided. Using that, I was able to reproduce the issue you were mentioning.

Please try the following snippet:

  instance.Core.documentViewer.addEventListener('documentLoaded', async () => {
    const doc = await instance.Core.documentViewer.getDocument();

This code snippet enables z-order reading order, which helps read documents such as these. I was unable to reproduce the issue with this code.

Let me know if this works for you!
