msv0001 : strange, I don't have that bug. Can you provide the .capx ?
@arcalaus : I see what you want to do. I need to add a function to the plugin to do that (substract or XOR).
@inkBot : since everything is calculated in JS (no WebGL shader), when the size is too big (1024� seems a bit heavy), and if your machine isn't ultra-recent, if think the calculation is going to be killed byt the browser after some time. NEver had any problem with texture of 512� and under.
@LittleStain : it's a bug in the display in the IDE, it's working when you run it, (at least it should).
