Now testing on my netbook with an 'Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)' graphics adapter. Tree animations works with no issue ( ). Parallax mapping works nicely in Atlas: It also works in-game, though lightning of the terrain flickers back and forth several times a second (normal, darker, normal, darker etc.) If I disable GLSL, there is no flickering. If I enable GLSL with the unpatched master branch, I also experience flickering. (Conclusion: Flickering not due to your changes, but due to a problem in the GLSL support, hardware or software.)
