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

Rendering code looks fine, and I have a hard time seeing any artifacts in the gif, but do you maybe set x/y to fractional numbers? Because that would result in slightly different image filtering depending on the exact subpixel position.

Ah, yeah x & y were floats and sometimes fractional. I changed it to only position to integers and it seems to have fixed it.

Thank you!
