I’m working with OJS 188.8.131.52, there is something strange in PDF rendering with the plug-in.
On Windows10 and MacOS with Chrome and Firefox.
Look at the double letters at the centre of this screenshots:
The letters ff are carried to the left over the previous part of the word.
But everything works well with if you download the pdf or if you’re using Linux (Chrome and Firefox) and Windows 10 with Internet Explorer e Edge.
Did someone have the same problem?
