--- Comment #1 from tt_1  ---
I get these from the logs of my cmdline:

014c:fixme:d3d:wined3d_swapchain_init The application requested more than one
back buffer, this is not properly supported.
Please configure the application to use double buffering (1 back buffer) if
possible.
016c:fixme:d3d:state_linepattern_w Setting line patterns is not supported in
OpenGL core contexts.

I'm happy to debug this with wine-debug, but I need guidance on how to do it
properly please.
