When enabling MSAA, artifacts appear and texture lookups fail on edges

Question

On the edges of my cubes, lines with RGBA 0, 0, 0, 0 appear as texture lookups on that position fail. I have colored the texture lookups that failed magenta in my fragment shader.

Should I render to a texture first, bind it to a quad and perform the MSAA afterwards instead of per cube?

Maybe it samples pixels that are not filled yet.

Binding to a quad first does not help. Maybe it needs to know the vertices to perform MSAA? — Z0q, Oct 15 '15 at 10:58

Using GL_CLAMP_TO_EDGE instead of GL_CLAMP_TO_BORDER solved the issue.
