I'm runing spring under Ubuntu 8.10 (Intrepid). I have an Nvidia GT8800 and two screens. I'm using the TwinView option in the "NVIDIA X Server Settings".
Here is my problem/bug when i launch a game :

Interesting, isn't it ?

I tryed to change resolution in spring options with 2560x1024 but it doesn't works too, same for the dualscreen option ...
Any idea ?
