As illustrated below, I occasionally encounter (but cannot recreate) display issues with mupdf on Linux Mint 17.2, whereby parts of the display turn black
and whereby all or parts of text being garbled
(The above shows garbling of black text and blue text.)
I have also observer some other issues that I forget.
What is going wrong?
UPDATE (18 Aug 2017). This issue persists in
mupdf-x11 v1.11, but not in
mupdf-gl v1.11, so I presume there's a problem with X or mupdf's interaction with X.
