Thanks for your answer! Right, I could clear/redraw the control only partially. This would reduce, but not completely avoid flicker and would raise the complexity of the code.
I'm still looking for copying, instead of drawing. I just saw that cairo uses the CAIRO_OPERATOR_OVER compositing operator by default, but it could be set to CAIRO_OPERATOR_SOURCE before drawing my buffer and then set it back. Is that a way? How can it be realized without modifying the System.Drawing.Graphics class (It still should build with .NET).
