Getting this error? If so you may want to check out your OpenGL Settings, specifically The texture memory, which in my case was set too hight. Here is the documentation taken straight from adobe:
To modify the amount of texture memory, choose Edit > Preferences > Previews (Windows) or After Effects > Preferences > Previews (Mac OS), click OpenGL Info, and enter a value for Texture Memory of no more than 80% of the installed video RAM (VRAM) on your video card.
Be sure to exit and restart after effects after lowering your settings.
