--- Comment #10 from Ian Stroud ianstroud@btinternet.com 2011-12-04 10:52:00 CST --- I'm not making any much progress with this. It appears that a call to IDirectDrawSurface7->Blt is sometimes failing with WINEDDERR_INVALIDRECT. There are a number of TODOs and FIXMEs scattered through the code which may or may not be relevant. This issue really needs help from someone with an in depth knowledge of opengl / directx to pinpoint the exact problem. I'm happy to help/test potential fixes where I can but at the moment I'm just working blind.
