Is the X dbe extension being deprecated?

[bolta...@boltar.world]

Hi

I've written a number of C & C++ X windows apps that use the double buffer
dbe extension but I've noticed that the performance seems to be getting
worse and worse on Linux these days and with compiz effects switched on
it pretty much crawls. Is the double buffer extension being slowly being
deprecated and if it is , is there an alternative to use with the basic
Xlib API? I'd rather not have to learn OpenGL or DRI just to get smooth 2D
graphics.

Thanks for any help
