In multiwindow mode the modal moving/resizing of windows causes a lot of redraw events to be sent to the X clients after the user releases the mouse button. During the moving/resizing client windows are not redrawn as long as the mouse button is pressed, but all redraw/resizing events are queued and executed step after step after the moving/resizing ends. Some clients collect and combine multiple redraw or resizing events, other clients (e.g. xterm) simply execute each redraw or sizing event. The enclosed patch minimizes the events for clients to only one event after the user releases the mouse button to end the moving/resizing. This improves the user experience and reduces strange screen flickerings, especially on slow platforms. The enclosed patch modifies winmultiwindowwndproc.c such that the windows events WM_ENTERSIZEMOVE and WM_EXITSIZEMOVE that are sent by Windows when the modal window resizing/moving begins or ends are considered. Only after WM_EXITSIZEMOVE is the redraw/resizing executed.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
