[Misha <fomisha@xxxxxxxxx>]

I'm on Ubuntu 15.10
using 
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)

When using some java applications (specifically Interactive Brokers
TWS), about 10% of the time Ubuntu cannot figure out the size or the
position of the window or which window is on top. So, you click on one
window and miss or an action of another window (the one behind) is
activated. This usually gets fixed by system reboot or

wetsid unity

I have not seen this behavior with any application other than TWS, which
is a java application.  I would be happy to provide more details.

Title:
  Unity: wrong window dimensions / location in Java applications

Status in Compiz:
  Fix Released
Status in Compiz 0.9.9 series:
  Fix Released
Status in JOSM:
  Unknown
Status in compiz package in Ubuntu:
  Fix Released
Status in openjdk-7 package in Ubuntu:
  Confirmed

Bug description:
  In Java applications, the functions to set and get window dimensions
  and position do not work as expected. This problem is only observed in
  Unity but not gnome, Win., etc.

  Details:

  * Call setSize(200, 200) and setLocation(300,400) for a JDialog
  object.

  * If you call getSize() and getLocation() directly after making the
  JDialog visible, the result will be (200,200) and (300,400). Calling
  getSize() and getLocation() again, a split second later, the result is
  now (200,200) and (301,428). In both cases, the values are wrong, the
  size and location is actually (202,229) and (300,400) as shown by a
  screen capture.

  Consequences:

  * If the dialog is designed to reach to the bottom of the screen, the
  lower end will be cut off about 30 pixel, so the window needs to be
  moved by the user each time to see the lower button row (e.g. settings
  dialog in netbeans on medium resolution screen).

  * In applications that save and restore window position and size, the
  window will move down 28 pixel each time it is opened an closed (e.g.
  JOSM, preference dialog).

  Expected behavior:

  * The result of getLocation() should be constant for one window unless
  the user moves the window

  * setSize(dx,dy) should not set the size of the content pane, but the
  size of the entire window, including window decorations

  * be consistent for all Window objects, e.g. in the attached sample,
  the JFrame works correctly, but the JDialog shows the described bug

  Output of the sample code (press button "click", then press button
  "click2"):

  dlg.getLocationOnScreen()=java.awt.Point[x=300,y=400]
  dlg.getLocationOnScreen()=java.awt.Point[x=301,y=428]

  Note: Both getLocation() and getLocationOnScreen() return the same
  values.

  Observed for the following Java versions:

  java version "1.6.0_24"
  OpenJDK Runtime Environment (IcedTea6 1.11.5) (6b24-1.11.5-0ubuntu1~12.10.1)
  OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

  and

  java version "1.7.0_09"
  OpenJDK Runtime Environment (IcedTea7 2.3.4) (7u9-2.3.4-0ubuntu1.12.10.1)
  OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)

  Ubuntu 12.10

  unity-6.12.0-0ubuntu0.2

  update: same behavior in gnome classic with compiz running
