Hi, my game does not run as espected on some browser, it runs perfectly fine on desktop browsers though.
One of my sponsors which I sold a license to told me that the game does not show graphics as they should.
This is what the game looks like with iPhone 4s:
The grid should not appear, I don't know where that grid comes from.
Also, on galaxy s2 and s3, when I change tabs on the browser and come back to the game, the game freezes.
I only have a galaxy s2 to test, the other devices where used by my client.
Any idea of how can I start to solve this problem?, what should I find out first? what do I need to learn?. Please help since I am not experienced in mobile browsers, any hint is appreaciated, thanks.
