Dear list, with current latest (LuaTeX 2.06 20200717 + ConTeXt MkIV 2020.07.20 10:48), I cannot open luametatex.pdf (its SHA256 reads cff8b660b65f4f8c121c170bcd59545c5467a7db02614da137e622ef1c5f3964). Acrobat for Linux complains about malformed document and Evince doesn’t display anything. Latest mupdf-gl complains about broken xref (mupdf complains too): error: cannot recognize xref format warning: trying to repair broken xref warning: repairing PDF document I experience issues in Windows with current latest: \starttext \input zapf \stoptext The output PDF document opens in SumatraPDF fine. But in Acrobat DC, no character is displayed. Could anyone confirm the issues with current latest? Many thanks for your help, Pablo -- http://www.ousia.tk
