+\twocolitem{msw.window.no-clip-children}{If 1, windows will not automatically get the WS\_CLIPCHILDREN
+style. This restores the way windows are refreshed back to the method used in versions of wxWidgets
+earlier than 2.5.4, and for some complex window hierarchies it can reduce apparent refresh delays. You may
+still specify wxCLIP\_CHILDREN for individual windows.}
+\twocolitem{msw.notebook.themed-background}{If set to 0, globally disables themed backgrounds on notebook
+pages. Note that this won't disable the theme on the actual notebook background (noticeable only if there are no
+pages).}
+\twocolitem{msw.staticbox.optimized-paint}{If set to 0, switches off optimized wxStaticBox painting.
+Setting this to 0 causes more flicker, but allows applications to paint graphics on the parent of a static box
+(the optimized refresh causes any such drawing to disappear).}
+\twocolitem{msw.display.directdraw}{If set to 1, use DirectDraw-based implementation of
+\helpref{wxDisplay}{wxdisplay}. By default the standard Win32 functions are
+used.}
