I'm positive this has been asked before (I did a search on the old group), but there was a reference on a post to riq where it was supposed to be fixed in a new version... But I'm still having the same problem.
[UPDATE]: I'm using cocos2d from svn trunk
When using TileMapAtlas, I get a small gap between the tiles. My tilesheet is a png 1024x1024 and the tiles with problems are not tiles in the border of the tilesheet, actually, those look just fine...
The gap seems to vanish if the sprites approach the middle of the screen... Any idea on how to fix this?
PS: here are some screenshots on the issue:


Thanks!
