Color / Texture Fill Glitches (pictures included)

[A20022970]

This happens constantly, with every project I do. It happens regardless of the color/texture. I’m not sure how to adequately describe it, so I’ve uploaded some pictures a picture with this thread (new users can only post one picture) - does anyone know why this is happening and how I can prevent it?

OS: Windows 7 Professional x64
Version: 17.2.2555.0
Memory: 8 GB

I will add that this happens with or without circles/curves. It will occur even with a perfectly square/straight lines only layout, and regardless of its size. It is unstable and changes as I rotate.

It looks like Z fighting. Two faces overlap and they are fighting to be seen. Get rid of one of the faces and the problem will be gone.

My gut feel from looking at your image is that you are experiencing a z-fighting situation. Try increasing the thickness of your circle before applying the texture.

It should also be pointed out that you are painting the back faces.
SU has front and back faces,
The white faces are the front and are the ones that should be seen.

Sorry DaveR, I think we were both responding at the same time.

Adding some more pictures.

Adding more pictures only makes the issue clearer. You are seeing the results of Z-fighting.

Basic Z-Fighting.
