Well, the same problem happens at my home and at my work PCs. Both are with up to date video drivers.
It only happens when exporting the project to Node-Webkit, not just previewing it.
Not sure at work, but here at home i got NVidia GTX 560.
Sometimes the ground texture is not stretched, but just looks very low rez, nothing like how it looks at Chrome.
Can anyone confirm that Exporting to Node-Webkit gives that bug?
Btw 7Soul I made it like this because of texture resolution. I got 2 tilable backgrounds and low rez mask, so i got better resolution for lower texture size.
