Hi, 

With newest ubuntu 14.04, valgrind detectes this one :

104 bytes in 1 blocks are definitely lost in loss record 97 of 152

Hi.

That looks like a bug in mesa, as I've checked X11_GL_GetVisual and glxChooseVisual calls (which is called inside X11_GL_GetVisual), and everything it returns is free'd later before returning from the calling function (the one calling X11_GL_GetVisual).
