--- Comment #1 from Henri Verbeet hverbeet@gmail.com 2013-11-19 12:49:12 CST --- That commit is correct in principle, but the issue is that the application creates a IID_IDirect3DRGBDevice device on a surface that has DDSCAPS_SYSTEMMEMORY set. Contrary to HAL / TnLHAL devices, RGB devices can render to sysmem surfaces.
