Visible seams between tiles

I have problem with tiles. This video will show you exactly what is the problem:

As you can see, there is visible seam between tiles. Sometimes it is more visible - sometimes not that much. It is getting worse while I drag tileset around…
I am using new Image Groups and ImageSheet in png format.
All tiles are matching perfectly and alpha is not blurred…
All tiles are grouped and that group has physics applied to it because I am using LinearImpulse.

Am I doing something wrong here? Is this a bug? [import]uid: 101952 topic_id: 27840 reply_id: 327840[/import]

We have a few threads about this, this is probably one of the more helpful; http://developer.anscamobile.com/forum/2011/06/03/lines-between-my-tiles

Ignoring the issue for a moment, your game looks really interesting! [import]uid: 52491 topic_id: 27840 reply_id: 112748[/import]

Thank you Pellen

It looks like OpenGL thing. I’ll try to recreate tiles with 2px border (as Walter mentioned in that post) and see if it works. If the problem still exist - I’ll be back.
