glxinfo output

I have a radeon HD4650 PCIe running in archlinux 64 bits OS,

I use the r600 driver,

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV730
OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.0.1 ( you can
fin full gxinfo output in the attachement with this message )

Since I upgrade to Mesa 10.0.1 I notice missing trees in flightgear 2.12.1,

on startup I can see trees, vegetations, but if I maximize the windows or if I
start the engine or move the plane the trees disappear,

it's a weird bug because sometimes the trees appear again when moving the plane
or using a different point of view ( tower, outside the plane ), but instantly
these trees disappear again when I return in the cockpit of the plane,

see the attachements with this mail ( 2 screenshots, one with the trees
displayed, and one when the bug occurs, no trees ),

I think it's a bug from mesa 10.0.1 because with mesa 9.2.5 I don't have this
bug
