Composited environments -- disable GTK double buffering?

[Vytautas Liuolia <Vytautas Liuolia gmail com>]

Hello,

I have been experimenting with a simple GTK program, where I turn off
double buffering and drawing works fine (well, or almost fine) under
composited environment. Maybe GTK double buffering could be disabled by
default (fixing issues if any) on composited environments?

I'm not a big expert of these, but under my impression, compositing
manager (like Compiz) first lets an application to do the drawing to the
off-screen pixmap, then transfers that data to OpenGL texture. If we set
up everything correctly, no double buffering on GTK side should be
needed.

Best regards,
Vytas
