Cannot place the link cursor on some part of graphic window

Hello
I have a weird problem:
After resizing a display window, I can only move the link cursor (by clivking) to a restricted rectangle of the window.
Has anyone else experienced the same problem???
Could it be an OpenGl problem with my particular video controller (Intel 950).
If yes, I guess it's time to change my notebook (even it is only six months old...).

Well, it looks like it is linked with your other problem... I guess there is a bug in OpenGL or the 3D driver.
BTW, some people had problems in 3D rendering with some Mesa OpenGL (coming with Xorg) a few months ago, which also appeared with Intel chipsets (but not only Intel chipsets). It was a different problem (polygons rendering), but upgrading Mesa/OpenGL solved it. Is your Linux up to date ?

Problem with rendering polygons

Hi Denis,
Indeed I'm currently having a problem with rendering meshes in Anatomist.. Whereas rendering volumes in 3D windows doesn't show any issue, as soon as I load a mesh in a window, I get this curious result :
I just installed Mandriva Powerpack 2007, it wouldn't be surprising that it has something to do with this bug ; still, would you any idea of how I could solve this ?
Many thanks !

Hi Grégory,
This is a bug in Mesa (non hardware accelerated OpenGL implementation). You must either install the appropriate accelerated driver for your graphic card or download and install a newer Mesa version than the one provided with Mandriva.

Woow, funny...
That's typically what we obtain with the buggy Mesa...
Upgrade or recompile Mesa and it will be better.

Hello !!
I had this problem (same display as the snapshot that Gregory sent) with Fedora Core 6 - 64-bit. I tried to recompile Mesa for 64 bit, but it didn't work whereas when I recompiled Mesa for 32 bit it worked. Here is what I have done, in case it help someone :
download MesaLib-6.5.2.tar.gz (on
http://www.mesa3d.org/)
tar zxf MesaLib-6.5.2.tar.gz
In Mesa-6.5.2/ type :
>> make linux-x86-32
then
>> cp -r include/GL /usr/include
>> cp -pd lib/* /usr/lib
It works perfect now ! (Maybe it is not so good for other applications, but... I do it anyway !
If something happen I will let you know )
See you !

Hi,
I understand why recompiling Mesa 64 bits did not change anything for anatomist: our binary distribs are built for 32 bits, so they use the 32 bits Mesa. 64 bits linux distribs have both variants of (almost) all libraries, but it depends on the program wheter it uses the 32 or 64 bits one.
