When I put two images next to each other then move both simultaneously I get a one pixel wide drawing artifact. It looks fine one second but then the artifact appears when you move the two pictures. Here is an example:

Does it have something to do with antialiasing in Starling? Antialiasing in the texture? Image positions on non-integer positions?

I do not want to overlap the images. Any ideas?

That's an aliasing error that is hard to avoid in GPU programming. The workaround is to use a tool like "TexturePacker" to create your atlas, and use its 'extrude' setting.

Another workaround that could help is to cast the object positions to integer values.
