Jagged circle, opengl, painters 3d plot

Hey everyone,

While using matlab my graphs keep coming out horrible. When the opengl renderer is used I see jagged lines (circle) and when using painters I have no alpha. On top of that it's a 3d graph. When I save it as an emf file it give a decent output but creates white lines when zooming in and out, with the white lines being at different locations when you zoom. When I save it as a png (or jpg, pdf, etc) I have a jagged circle with and uneven line thickness, while the Z is constant.

I checked the PC I was using and it didn't have opengl support (opengl info)

SupportsGraphicsSmoothing: 0
SupportsDepthPeelTransparency: 0
SupportsAlignVertexCenters: 0

So I used a different PC that did have a 1 value for all of them but I kept getting the exact same problem. Does anyone have any idea what's going on here? And do you maybe know a good solution?

You can see the difference between a emf and png in the picture below.
