Hello Guys!

I had this problem for a long time, and one day I decide finish with this issue.
What you have to do, is work with “open GL – always on”. In the Composition Screen, find the icon of Fast Previews and choose: (“open GL – always on”). After this, a icon of Open GL will appear in the top of the Composition screen”.
But this only help you during the edition process.
To render the work without the lines, you have to enable the Open GL Renderer. How do this?
Open the Render Settings (Render Queue) and above “Disk Cache”, find the option: “Use Open GL Renderer”.

More about open GL:

OpenGL is a set of standards for high-performance processing of 2D and 3D graphics for a wide variety of applications. For After Effects users, OpenGL provides fast, high-quality rendering for previews and final output by moving rendering from the CPU to the OpenGL hardware (GPU).

To use OpenGL in After Effects, you’ll need an OpenGL card that supports OpenGL 2.0 and has Shader support and support for NPOT (Non Power of Two) textures.
