Description
Following on from the 'XvMc?-OpenGL and OpenGL-OSD' thread (http://mythtv.org/pipermail/mythtv-dev/2008-May/061934.html) on the myth-dev mailing list, here is a patch to fix the issue that appears on certain NVIDIA cards.
I think it may also fix http://svn.mythtv.org/trac/ticket/4813 so tafypz may want to give it a try.
The patch simply modifie get_fbuffer_cfg() to add an GLX_ALPHA_SIZE component to the kRenderRGBA glx_fbconfig parameters passed to get_pbuffer().
This function is also called from openglcontext.cpp so I don't know if it will have any impact there. If it does, then I propose we add a new FrameBufferType?=kRenderRGB support the openglcontext.cpp use (as it currently is only RBG not RGBA).
Hopefully, this can be applied as-is, otherwise let me know and I will work on a more extensive patch.
