Description:
Hello, excuse me I use Linux Ubuntu 18.04.6 and LibreOffice 7.4.0.3. i insert a Chart with Click on "Insert Chart" in LibreOffice Calc or other Softwares (LibreOffice Writer, LibreOffice Impress and etc) i can't Apply Persian Font that solve by Enable "Complex text layout" on Language Settings but after export PDF or maybe Print (of course i am not sure about printing because I have never printed a file.) Persian Words of Chart have Underline some Words but this problem doesn't happen in Software (for example LibreOffice Calc) that i insert chart and if i export chart as image and select SVG format and insert that Instead Chart and then export PDF this problem doesn't happen.

i think should report this problem to solve it if this is a problem.
and maybe scroll of opacity of an object (for example a chart background) has a little problem because when changed, percent change but scroll doesn't change, that's mean scroll doesn't change which after click on a empty part in sidebar scroll change, but percent change and apply anyway.

this is the link of font that used in test file:
