Issue with Particle System Quad in Retina

Hi!, I just want to report an issue, not sure if is a bug or not…

I have some particle effects I made in ParticleDesigner. cocos2d-x uses the .plist file with the embeded texture… and it display correctly, using a call of this kind:

@
CCParticleSystemQuad* fire = CCParticleSystemQuad::particleWithFile(“fire.plist”);
this~~>addChild;
@
However, and depending on the configuration of your particle effect, the X axis seems to have a weird behavior on the Retina Display. Some particle systems appear several pixels more to the left, and some times , just the “left part of the fire” appears…
But if you load the particle system as Point instead of Quad… just like:
@
CCParticleSystemPoint* fire = CCParticleSystemPoint::particleWithFile;
this~~>addChild(fire);
@

everything works OK on Retina.

Im using the last version cocos2d-1.0.1-x-0.11.0
