SUMMARY

Some windows on some screens resize to 132 pixels height (width unchanged) and move to the top of the screen, some time after the system has been in screen saver.  Not all windows get resized.  Not all windows for a certain application get resized.  One monitor's (the lowest priority) windows don't seem to get resized at all.  It happens on all 6 of my virtual desktops.

It occurs some time after the system switches to screen saver mode, but not immediately...switching the screen saver off quickly shows that the resizing hasn't yet happens, but I haven't any idea when it happens, or how to find out.

Before and after screenshots are attached.
