Hi,

here is Klaus from krpano.

In that example these texts will be drawn using canvas + filltext and then that canvas be used as webgl texture, nothing really special.

Providing the example without minification and without obfuscation is unfortunately not possible and might be also not really helpful as it would be a lot of lower-level engine code. But the code/API-calls should be not the problem.

I wasn't able to reproduce that either, the example was tested on a lot of different systems, but nowhere with such problem. That seems to be somehow specific to Arthurs system...

When looking at the screenshot it seems like the wrong characters are used, but that equal for all texts - see the 'Image' texts and the 'e' and 'b' in the 'Web' and 'Youtube' texts.

If necessary I could make a special build where all filltext calls will get logged to console.

Best regards,
Klaus
