--- Comment #3 from Michael B toxatec@web.de --- (In reply to Michael B from comment #2)
So first, WINED3D_SWAPCHAIN_NO_WINDOW_CHANGES is not being set in ddraw:ddraw_attach_d3d_device() since commit f90d607c67768f19e36d9d74b498594252faa3fd
Of course that flag *is* being set since that commit, sorry. I submitted by accident before I could check it again.
