Created attachment 184233 [details] A test file that exhibits the described problem. The attached PDF file contains the example text `H∑y` set in JuliaMono. The middle character is the summation sign (U+02211). In JuliaMono the summation sign goes up slightly higher than `H` and goes down as low as `y`. But Okular displays it shifted upwards, so that it sits on the baseline instead. This problem disappears with a zoom of at least 1,839%. STEPS TO REPRODUCE 1. Open the attached PDF file. 2. Zoom to 1,838%. 3. Zoom to 1,839%. OBSERVED RESULT When the file is first opened the summation sign sits on the base line. Zooming to 1,838% doesn’t change that. Zooming in one percent further to 1,839% makes the summation sign suddenly drop down as low as `y`; it is now only slightly higher than `H`. EXPECTED RESULT The summation sign should be positioned correctly even at normal zoom levels. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux (fully updated) KDE Plasma Version: 6.4.4 KDE Frameworks Version: 6.17.0 Qt Version: 6.9.1 ADDITIONAL INFORMATION - The file was created with LuaLaTeX. - The problem does not seem to occur with other PDF viewers or with programs that can import PDF files. I’ve tested Evince, Xpdf and Firefox, and I imported it in Inkscape, Krita and Gimp. - I have only experienced the problem with this specific character (the summation sign) in this specific font (JuliaMono).
