Hi, I hope someone could help me, i have trying several versions of Wine and each time i get this problem with my software when i move windows : [Image: http://img171.imageshack.us/img171/6274/sanstitrebo.gif ] I am running with Ubuntu Jaunty and Gnome environment. My graphic card is an Nvidia Geforce4 and i have installed the Nvidia drivers. I work on a dual screen. Actual Wine version is 1.1.17 but it's the same problem with 1.1.29 and other... I have trying multiple options (émulate virtual desktop, don't emulate, activate/désactivate Vertex Shader...), désactivate Compiz (3D cube, etc) an nothing can solve my problem. Is someone got an idea ?
