Hi,
in multiwindow mode the modal moving/resizing of windows causes a lot of
redraw events send to the X clients after the userse 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 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 are considered that
are send from windows if the modal window resizing/moving begins or
ends. Only after WM_EXITSIZEMOVE the redraw/resizing is executed. The
patch is against the sources of xserver-cygwin version 1.10.3-1.
Best regards,
Oliver
