In consequence, the backend map is considered not to be correct... or unknown as the appropriate case statement is missing. So, I modified your debug statement to additionally show the expression of the switch statement. On my system, the output is "5". Needless to say, that there is no "case 0x05:" statement yet :-) Does a "5" make any sense to you?

There are some minor gliches with transparency, that appear if you active a context menu (right mouse button). Then, you only see the icons and the text, but not the window itself. If you hover the mouse over it (to trigger repainting), than the window appears as well. glxgears works. Nice.
