Hello,
Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-8142534
webrev: http://cr.openjdk.java.net/~ssadetsky/8142534/webrev.00/
In Ubuntu starting version 15 the current active windows gets an
external translucent shadow which serves as a sensitive border for
resizing. So all mouse clicks that fall into ~10 px distance around the
active window belongs are captured by WM, even if another window is seen
at the click point.
In the test 2 windows are created beside to each other and in the second
step of the test a mouse click is emulated to activate the 2nd window
menu, but the click happens in 5px from the 1st window edge which is
active and captured by WM as the 1st window resize event.
To fix this Ubuntu specific issue the suggested patch increases the
distance between two windows by 50 pixels.
