Almost invisible lines


#1

In this PDF, in the last page, the lines are very thin and almost invisible, although it displays properly in pdf.js.

I’m using Sumatra 3.1.2 64bit on Windows 10

Hello
I really love Sumatra and try to use it as my favorite pdf reader. I find, though, some small limits.
One is related with lines display. I have the opposite problem, compared to aldofintel.
I have drawings where the line width is too large and I loose sight of small details.
Is there a way of toggling on/off the line width display, as in other pdf reader (typically, ctrl+5)?
