for me with my ati radeon HD4650 ( who uses r600 driver ) it's not a random
bug, the bug is always reproducible with flightgear 3.0.0,

the use case is simple : a C172P airplane and the use of the option
"Atmospheric light scattering", with my graphic card ati HD4650 ( and maybe
other models ) something goes wrong in the mesa code,

but I am not an expert in opengl programming, 

perhaps we must contact the author of the faulty commit ( Ian Romanick ) :


he may know the solution with the apitrace, a missing update of a variable
related to the R600 driver for example ?

I think also that someone who works in 10.2 branch has reverted this commit
because he found some bugs or strange results in test softwares like piglit ?
