Weird effects when exporting to Visual Studio (Win 10)

Is webGL supporter in Universal Windows Platform applications? I've used a few effects like vignette for esthetic reasons but they do not display correctly after compiling.

Am I missing something or should I Just steer clear of these.

Thanks in advance guys!

I can't help with those specific questions you posted, im not sure about whether those effects should work, but you might want to try building your win 10 UAP in XDK, just to compare. Have you tried?

I tried to build my game in VS and it seemed to break my game in all sorts of interesting ways. I had better luck with XDK, although it still wasn't perfect.

Thanks for the quick response, I'll try my luck, otherwise I'll just have to design my sprites better!
