Conventional wisdom (gleaned from Markus / Mozilla etc.) suggests that the mixture of OpenGL and DirectX in the same process is really sub-optimal from a stability perspective. As such - we should use the accelerated GL / VCL rendering model for slideshow in place of the directx canvas - so as to avoid using 2x different acceleration models; that is until the GL / slideshow code is in good shape.
