--- Comment #4 from Roderick Colenbrander thunderbird2k@gmx.net 2008-02-22 02:27:01 --- Roughly speaking the client area of an application is the area below the 'menu'. The 3d view of applications without a menu or with just a filemenu is a real X11 window now. Applications like Google Earth use 'child windows'.
The patch fixes a lot of Direct3D and OpenGL which only have a menu with a 3d view. Examples are Direct3D samples, Weatherscope and others.
Further right now there is a limit on the opengl pixel formats. This is the first step in lifting that limit. That will fix most remaining opengl bugs (a lot of apps are picky about the opengl formats, e.g. Sketchup). Second the proper format can improve performance upto 20% in some cases.
