I’ve received reports that PDFs generated by Mu͒seScore when viewed in Atril (but not in Okular or mupdf!) have the top of the treble clef cut off. I found that the same happens for glyphs of the font I use for URLs and copyright notices (attached), but only from Mu͒seScore, not from LibreOffice. I first reported this to Atril both because I couldn’t find anything wrong with the font metrics (or after fixing what could have been, I tried multiple variants) upstream at https://github.com/mate-desktop/atril/issues/610 where a helpful soul found that there’s some clip path in the PDFs which Atril honours that clips off the rendering but that under that the glyphs are fully present. Then I dug into the Mu͒seScore Studio source code, but could not find anything suspicious, so I extracted an MWE from its source code (under GPLv2 though I doubt the example below is actually nōntrivial enough to be copyrightable) to generate a PDF and, voilà, the top of the text is cut off in Atril but not in mupdf. I’m attaching the MWE (qex.pro + qex.cc) and the font file (SIL OFL, currently the .otf is the source) so you can reproduce this. It reproduces for me on stretch, bullseye and sid, probably universally. (Make sure $DISPLAY is set. Put the .otf into ~/.local/share/fonts/ to test.) $ QT_SELECT=5 qmake qex.pro && make && ./qex $ mupdf moo.pdf $ atril moo.pdf Please forward this bug upstream as suitable. Thanks in advance!
