Hello, I've currently been experiencing visual artifacts in both the osx and html5 builds of a very simple program using Kha's graphics2 (project source).
I have captured a gif of the html5 artifacts I am seeing right here.
If you look near the middle of the right wing as the ship is moving in that gif you'll notice that there seems to be a slight tear, although it doesn't appear to go all the way across the sprite. OSX has similar artifacting, although it is seemingly in a different place.
I am not 100% certain but it almost seems like the artifacts bubble up when the ship is in specific areas on the screen.
Is there anything I am doing wrong (the rendering code starts here and the actual rendering for the ship in question is here.
Any help is greatly appreciated!
edit: I am running osx 10.10.5, and I am testing the html5 output in Chrome 46.0.2490.86
