Yes, as far as I know, Mesa driver for HD7700 is not complete. You say you had no problems with which Mesa version? I think you should try to disable the shaders in Flightgear or use the proprietary driver.

Once I disable Generic in Shader Options the strange colors and flickering disappears. None of the other options have any effect.

I last saw Flightgear work with full shader was with Mesa 9.1.1. Once mesa got updated for mga3-RC the strange coloring appeared.

I suspected it had to do with mt 7700HD-card. How do I switch to proprietary driver? Do I need to relink?

Looks like a regression came so. But are you sure you were using Mesa and not FGLRX?

No, it is much easier than that : in MCC click on the video card like show in the link below, it will ask you if you want the proprietary driver. Of course, non_free media must be enabled.

Comment 5 Hans Micheelsen 2013-05-25 20:27:39 CEST

Well. this is kind of embarrassing. I always thought that mesa was a layer over fglrx.
But anyway, yes I use fglrx. I just checked /etc/X11/xorg.conf. It says:
   Driver "fglrx"


One question, though. According to rpmdrake the only package that provides /usr/lib64/libGL.so is lib64mesagl1.
And /usr/lib64/libGL.so sym-links to /usr/lib64/libGL.so.1, which links to /usr/lib64/libGL.so.1.2.0
The x11-driver-video-fglrx package only provides â/usr/lib/fglrx/libGL.so.1 and /usr/lib/fglrx/libGL.so.1.2. Is there a possibility to re-symlink /usr/lib64/libGL.so to /usr/lib/fglrx/libGL.so.1 other than by manual ln -s ? How can I be sure that I reached all other necessary libs?

Comment 6 José Jorge 2013-05-25 22:33:55 CEST

We symlink the good libGL.so when driver is changed. You can get be sure reading  the output command glxinfo from mesa-demos package.

Please re-open if you can give more info...
