Hi, I think, there is a problem with mouse polling in multiwindow mode (XWin.exe :0 -multiwindow) in Cygwin/X 1.13. If a window gets maximized and then minimized, it will receive motion notify events, whenever the user moves the mouse cursor over the screen. To reproduce the problem, please follow these steps: 1) start XWin.exe in -multiwindow mode 2) start xev 3) maximize xev window 4) minimize xev window 5) move mouse cursor around and watch xev output You will see lots of MotionNotify events from all over the screen. X.org does not show this behaviour and I think, Cygwin/X should not either. The problem is caused by the WIN_POLLING_MOUSE_TIMER_ID, which doesn't get stopped, when the user minimizes a window. I made a small patch against Cygwin/X 1.13.0-1 which will stop the WIN_POLLING_MOUSE_TIMER_ID, whenever the user minimizes a window. If the user changes the window's size again, and the timer was stopped, it will be started again. The patch introduces a new flag in s_pScreenPriv to remember the state of the timer.
