Blank viewport in Linux

I'm running Draftsight on Fedora 17 64bit, but I can't use it since in vieport everything is missing [cursors, axis, grids, and, if I open an existing drawing I can only see a few lines, not the whole content]. I've tried to re-install DS and to delete all the config files previously created, with no success. I'm running Drafsight on another PC with same OS on, and it works fine! The only difference is that the computer on which I'm experiencing this problem is running an nvidia Quadro video card with nvidia drivers.

 

Here a screenshot of vp with cursor inside and grid on.
