Hi,
I have already managed to port glyph to the WebGL platform using emscripten and I have examined some strange behaviour. My build machine is Arch Linux x64 and everything works fine if I open the page form any linux machine either usung Firefox or Chrome, but when opened from the windows machine, I have some artifacts. It doesn't mather the graphic card as I tried with nVidia, Intel or Radeon. On the same computer (HP Z420 with nVidia Quadro 2000 graphic), linux display is OK, and windows display is damaged. Needles to say that I have the most recent drivers installed.
Here are the screenshots od the Helvetica.ttf font single period character (.) in the debug mode, fill and outline.






Any suggestions?
Regards.
