--- Comment #11 from Junfeng Qiao <qiao0junf...@gmail.com> --- I have the same experience for many other (scientific PDFs with many symbols) PDFs, when hinting is enabled, symbols disappear. Naively I thought text hinting would be good and should be turned on. Is it possible to fix this bug, or at least show a warning in the settings tab? -- You are receiving this mail because: You are the assignee for the bug.
