I did run into bug 16641, but there's a workaround: edit swapchain.c and device.c to force render_to_fbo on. I didn't run into bug 20307 - shadows work just fine.
About bug 20307, i'd say it's unnoticeable when running in a 640x480 window... I experienced it myself yesterday. But you can't miss it in 1680x1050 fullscreen. Toggling shadows on/off _really_ impacts the framerate. But this is off-topic :-)
How about the log i attached? One exhibits a GL_error, the other doesn't.
I'll test git hopefully tonight. May be should i regenerate a +d3d,+tid log?
