I am on debian 9.2 stretch with kde desktop on a laptop (DELL 5480),
I have a strange issue with okular: all was alright and now (maybe since the last security update) it doesn't read some of
my pdf files anymore especially those generated by Kile (even those generated a long time ago). Only mathematical symbol and pictures (if any) are displayed, not the text.
I tried with xpdf and also xournal and mupdf, xpdf produces the same result but xournal and mupdf read the files correctly.
Also okular print the files correctly.
I try also to change the fonts in okular back-end options without effect.
Now I edited a latex file with Kile and the problem disappears when the option
Code: Select all
\usepackage[T1]{fontenc}
Kile seems not related to the problem because files are printed correctly and also other readers works properly.
So it seems that the problem comes from okular but I do not know how to solve it?
