So I'm playing around with the GLSL in SDLMame. But, when it launches the cursor is moved to the center of the screen and doesn't go away until the mouse is moved. If I change the ini files' VIDEO option to SOFTWARE then it doesn't happen. I'm running in full screen mode. I've tried the -nomouse & -noui_mouse as a parameter too.
Is there a way to keep the cursor hidden while using opengl?
