Description Gauthier 2025-03-15 10:26:03 UTC 
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
