SUMMARY Some PDFs (cannot replicate for all) get blurry for certain levels of zoom, but only when going from less to more zoom. STEPS TO REPRODUCE 1. Open PDF 2. Zoom in (sometimes 125% is blurry, sometimes 150%) 3. Zoom out (is not blurry anymore) 4. (When a zoom level is found that makes PDF blurry) Zoom one more level (not blurry), and zoom out again (now not blurry). SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.23.90 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Kernel Version: 5.16.4-arch1-1 (64-bit) Graphics Platform: X11 Processors: 8 × 11th Gen Intel® Core™ i5-1135G7 @ 2.40GHz Memory: 15.4 GiB of RAM Graphics Processor: Mesa Intel® Xe Graphics ADDITIONAL INFORMATION This can also be observed in the integrated PDF viewer (preview) of Kile, for example. I'm using a global scale of 125%. If you cannot find a PDF where you can reproduce this behavior, I can share one where I observe this on two different devices.
Please attach the PDF and a screenshot of what you think it's blurred. Also are you running some hidpi screen and not 1:1 scaling?

(In reply to Albert Astals Cid from comment #1) > Please attach the PDF and a screenshot of what you think it's blurred. Done. > Also are you running some hidpi screen and not 1:1 scaling? 1440p on my desktop and 1080p on the laptop, both with global scaling set to 125%.
Can you try with global scaling at 100% and see if you can reproduce the problem?
With global scaling at 100% it's never blurry.
Also, just with X11. In Wayland it doesn't happen even with the global scaling at 125%.
Adding the x11-only keyword
