Hi could you post a capx with the error on and I'll check it out for you.
Wow, thank you so much for offering your help!
I'm attaching a smaller CAPX where the same error happens: https://www.dropbox.com/s/a53df6cn0rnlj ... .capx?dl=0
Apparently it happens because I'm applying a 2x zoom to the layer - and somehow tiledbackgrounds gets deformed when zoom is active.
I'll appreciate if someone finds a way to fix this *without turning zoom off* -- because I want to make the main game running in a low-res layer while messages and a few other things would run into a hi-res layer.
Thanks again and sorry for my bad English!
EDIT:
I've tested my game on my father's PC... And it's running perfectly with WebGL on.
My video card is an Nvidia (GTX 450) and his is an AMD (Radeon HD 6450).
I still don't understand what's going on.
WebGL on (AMD):
