Bug with TilingSprite._renderCanvas() (context not restored properly)

[Skeptron]

Hi all,

I'm using Phaser and I came across a glitch which is, I think, due to a bug in the PIXI.TilingSprite.protototype._renderCanvas() method. The bug might be linked to a bad restore of the context.

In my game, once I introduced tiling sprites, everything started to "slide". So I assumed that adding tiling sprites to the game introduced the "sliding" effect in the context. To prove me right I logged "context.currentTransform" at the start and end of the TilingSprite._renderCanvas() method, and I came across that result : 

Start of method : SVGMatrix {a: 1, b: 0, c: 0, d: 1, e: 0, f: 0}
End of method : SVGMatrix {a: 1, b: 0, c: 0, d: 1, e: -1255, f: -822}

So as you can see the e and f parameters are different. If I do a context.save() at the start of the method and a context.restore() at the end, everything works perfectly. Same goes if I hardcode context.setTransform(1, 0, 0, 1, 0, 0);

If it helps reproduce the bug, here are the values I have in the method : 

wt = {a: 1, b: 0, c: 0, d: 1, tx: -1255, ty: -822, type: 24}
resolution = 1
tx = -1255
ty = -822

tilePosition = {type: 25, x: 219, y: 0}
tileScale = {type: 25, x: 1, y: 1}

tilePosition.x = 219
tilePosition.y = 0

this._width = 4200
this._height = 2400

I'm not a Pixi expert (first post in this section!), nor in canvas/context, so I'm sorry for any mistake. Also I hope this has not been flagged already!

 

Thanks guys!
