            Bug ID: 501525
           Summary: Text opened and rendered one one screen gets blurry
                    when moving to a screen with different scaling
    Classification: Applications
           Product: okular
           Version: 24.12.3
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: PDF backend
          Assignee: okular-devel at kde.org

SUMMARY
When opening a pdf doc in okular, if I then move okular to a screen with a
different scaling (up or down), then the text currently displayed on the
document gets blurry (and so does any text that was displayed on the first
screen). If I scroll up or down to other pages the text is fine, but when I
scroll back to the page that was blurry it stays blurry. If I move back the
okular window to the original screen, then any text that displayed fine in
screen 1 (blurry in screen 2) display just fine again, and any text that
displayed fine in screen 2, now appear blurry on screen 1.

Blurriness only after text rendered on the document, not the text of the
application (menu etc.), table of content, etc.

STEPS TO REPRODUCE
1. Open  pdf
2. Move the okular window to a screen with different scaling 

OBSERVED RESULT
The text of the displayed page appears blurry

EXPECTED RESULT
The text should stay sharp
