Install CUDA made the Carla slow

Hi,

I meet a weird problem. All the thing works well in my computer at the first begining.

But after I installed the CUDA, the interface stuck.

If I open the Carla server, my screen stops, and my computer stuck.
If I open the Carla client, like the example, manual control, the interface stuck, although the fps shows a 50 HZ.

I noticed that Carla use OpenGL, is there some conflict about OpenGL and CUDA?

Thanks a lot!
