------- Additional Comments From hverbeet@gmail.com 2006-18-11 12:42 ------- Current git has a registry setting "HKCU/Software/Wine/Direct3D/OffscreenRenderingMode" to select the offscreen rendering mode. Setting that to "fbo" should fix the invisible terrain and the garbage in the sky. It will probably take a while before that becomes the default though.
