Bug Description

Window shade animation doesn't work any more, using the gles2 branch.

Press Ctrl+Alt+S. Windows do shade, but the animation doesn't work and the title bar vanishes and then quickly re-appears. This is only a problem with the animation plugin. Shading behaves correctly without the animation plugin.

The problem with the title bar disappearing was related to bug 1003255, which is now fixed.

But the shade animation still doesn't work.

I believe the problem is that the shade animation (rollup.cpp) uses GridAnim (grid.cpp). However, since grid.cpp was ported to GLES/GLVertexBuffer, the required functionality in grid.cpp to support the rollup animation is missing.

And I'm not sure it should be supported in grid.cpp any more. The standard shade animation is completely flat without any deformation. So it should not be using the GridAnim class at all. I think it the shade animation should be re-implemented independently without GridAnim in future.

This wasn't fixed in 0.9.11 am I right? At least it isn't working for me with 0.9.11 :)
