Some custom fonts that I have installed to capture text files were displaying correctly before the version 18 update using TEXT (GDI+) source. They still work with the Deprecated TEXT (FreeType 2) mode. I like to use Helvetica Neue font for my text file. I'm not sure, but I'm thinking that it might have to do with the fact that it's an .OTF file, as when I tried to use my only other font installed as an .OTF file (teamviewer11.otf), the capturing still did not work. It appears to work fine with any of the other fonts that I have installed, however. Again, this only started happening since the Version 18 update.
