Unfortunately a known issue due to usage of shaders on ATI Radeon.
Try disabling "Material Shaders" in the main menu: View -> Rendering Options -> Material shaders -> OFF

Yes, disabling "Material Shaders" rendering is okay.
I wonder why this does not happen with other aircrafts (i have not tested all of course) like 747, but I guess this is due to its rendering design.

Thank you

Ok. Doesn't happen with all aircraft, since only few use shaders so far (it's a new feature).

Problem is probably in line 58 of Shaders/lightmap.frag:

Should be

if ( condition >= 1.0 ) {

I'm unable to test this, and haven't checked it on NVidia either, but I'm 90% sure it's the bug. condition is a float, 1 isn't.
