          Priority: medium

3D works great but Blender fonts do not display correctly on my ATI rv280 9200
graphic card.

01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 PRO]
(rev 01)
01:00.1 Display controller: ATI Technologies Inc RV280 [Radeon 9200 PRO]
(Secondary) (rev 01)

The only workaround is to use:
LIBGL_ALWAYS_SOFTWARE=1 blender

My installation is on Mageia distro with KMS enabled (default):

glxinfo|grep render
direct rendering: Yes
OpenGL renderer string: Mesa DRI R200 (RV280 5960) 20090101  TCL DRI2

and with these packages:

x11-server-xorg-1.10.1-1.mga1
x11-driver-video-ati-6.14.1-4.mga1
mesa-7.10.2-4.mga1
lib64drm2-2.4.25-1.mga1
lib64drm_radeon1-2.4.25-1.mga1

I forgot to say that when I open the user preferences in Blender, Blender
crashes with:

X Error of failed request:  BadMatch (invalid parameter attributes)             
  Major opcode of failed request:  155 (GLX)                                    
  Minor opcode of failed request:  11 (X_GLXSwapBuffers)                        
  Serial number of failed request:  1007                                        
  Current serial number in output stream:  1008


So, the only way for the moment to be able to use Blender is to toggle
composite and run de special script ./blender-softwaregl :(

I managed to compile mesa git according to:
http://www.x.org/wiki/radeonBuildHowTo

with these options:

DRI_DRIVERS="radeon,r200,r300,r600,swrast" && ./autogen.sh --prefix=/opt/xorg
--with-dri-drivers=$DRI_DRIVERS --disable-gallium --enable-glx-tls
--with-dri-driverdir=/opt/xorg/lib/dri/

So I get now:
ldconfig -p | grep libGL.so
        libGL.so.1 (libc6,x86-64, Système d'exploitation ABI : Linux 2.4.20) =>
/opt/xorg/lib/libGL.so.1
        libGL.so.1 (libc6,x86-64) => /usr/lib64/libGL.so.1
        libGL.so.1 (libc6) => /usr/lib/libGL.so.1
        libGL.so (libc6,x86-64, Système d'exploitation ABI : Linux 2.4.20) =>
/opt/xorg/lib/libGL.so
        libGL.so (libc6,x86-64) => /usr/lib64/libGL.so

I'am going to reboot and see.

So.

It seems much better with git mesa. I've made a small try therefore.

No need to specify a GL variable to display the fonts, no crash when opening
dialogbox.

But there are still little artefacts when mouse cursor is "hovering" menus or
buttons.
