Comparison of firefox rendering (above) vs okular (below)
Here is a screenshot showcasing the issue, comparing with the good result of firefox. You can for instance consider the blue line below "Les + lus", but also the ugly line pattern in the title, the hard-to-read text etc.

Created attachment 168086 [details] Pdf that showcases the bug SUMMARY If I render a pdf file with a rotated image (produced via a simple \includegraphics[width=.6\paperwidth,angle=-10]{images/avantage_dwave.png}), the image is not aliased correctly, despite anti-aliasing being enabled in configuration > performances. The same pdf prints just fine in firefox. STEPS TO REPRODUCE 1. Open the attached pdf OBSERVED RESULT Observe ugly staircase-like pattern in lines EXPECTED RESULT This should be aliased like in Firefox SOFTWARE/OS VERSIONS Operating System: NixOS 24.05 KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.12 Kernel Version: 6.1.80 (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i5-8365U CPU @ 1.60GHz Memory: 15.5 Gio of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 ADDITIONAL INFORMATION
