[Dri-devel] Matrox G450 - drawing out of the window....

[Nicolas A. <Nic...@ep...>]

Hello

I have a Matrox G450 card on a RH7.1 Linux PC, XFree 4.0.3, and the
latest driver from Matrox (v1.3.0)
When running a OpenGL app., some strange things happen : if you move the
OpenGL window, the application does not crash, but the GL context does
not move, the rendering happens as if the window did not move (but
nothing is drawn outside the new window position, only inside).
Of course, no warning is shown, neither on the console, nor in the logs.
However, if you set the env. variable LIBGL_ALWAYS_INDIRECT, everything
goes back to normal.
Has anybody got a clue about this ?

Thanks in advance

Nicolas
