I'd like to use DirectFBGL for an embedded product with a Radeon chip, such that graphics is drawn with OpenGL and the (custom) GUI is drawn on top of that with DirectFB, with these two running in different threads.
The other approach, if there's no Radeon support soon, would be to draw the GUI with OpenGL too (using mesa solo). But then the GUI and the graphics would be synchronized by buffer swaps, with a negative impact on interactivity for the GUI when the graphics are complex and need long frame times.
Is there anything wrong in these thoughts?
