That's the trick, they are basically coding "links"...
Direct X calls linked to OpenGL calls.
And none of my other games are having issues...
But, with 2.8 and 2.9, I ran SH4 with wine set to "emulate a virtual desktop" of 1024x768, with SH4 set to the same resolution.
I started SH4 with the terminal to watch the output, and all is well, until I move the mouse then the errors that I noted previously start.
They stop when I moved the mouse to an area of the screen other than SH4.
So... I have no idea. I'm on WineHQ now to see if I can find any related bugs.
But all the other dx9 games that I have that I've tested work great...
