[Bug] Highlights do not align with text in PDF

For one particular PDF, when I highlight passages the highlights do not align with the actual text of the PDF. Strangely when I highlight that same PDF file in Adobe Acrobat, or even in the Zotero iPad app, the highlights perfectly align with the text as usual.

Additional information: it does seem to extract the entire sentences from said highlights in the Annotation tab. It seems to be a visual bug. Also, the left-hand side of the highlights seems normal/aligned with the text; it's the right-hand side highlights that look like a rotated histogram.

    Having this same issues with highlights misaligning for certain PDF's, and only on desktop Zotero for MacOS, aligns fine on iOS or Acrobat

    Zotero 7 beta will be out soon with an updated PDF reader, so you should test with that when it comes out and let us know if the problem persists.

    It should be noted that his issue is not unique to Zotero (6.0.27) but also exists in Okular (23.08.1) and Firefox (117.0.1) so the root of the problem may be in whatever is the intersecting factor of these.

    Alignment is correct in applications such as Microsoft Edge (117.0.2045.41) and in the Reader module of PDF24.
