---- Reported by milvich 2004-05-25 07:27:36 ----

When resizing or moving a window with a GLCanvas inside I will sometimes lose
the back buffer, and all my GL commands draw in the front buffer (with nasty
flickering results). This started happening when I upgraded to a Nvidia Quadro 4
XGL video card. It did not happen with my old video card, a Nvidia Geforce4

I have tested it on both my application and on the jogl demos with the same results.
Machine Specifications:
Gentoo Linux 2.6.5 Kernel
Dual Opterons
Nvidia Quadro 4 XGL 128 MB video memory (in dual head mode)
Nvidia 5336 Driver

I haven't seen a problem like this. Please try with the forthcoming 1.1 b08 and
if the problem still persists please try specifying
-DJOGL_SINGLE_THREADED_WORKAROUND=true on the command line and see if that
changes the behavior. If the problem is still there, please reopen this bug.
