Bug Description

I was on 14.04 and had no problem, but I started to have EQ overflow after upgrading to 14.04.3.
Then I did fresh install of 16.04 on the same PC, but still EQ overflow occurs after closing SMPlayer.

The only time this occurs for me, is when I try to close a java application (https://www.interactivebrokers.com/en/index.php?f=16045). With this particular java application, it appears to happen more often, if I use the window close button instead of the menu close item when closing windows (but always it occurs when attempting to quit, so it appears to be related to releasing memory).

This occurs for me when I send inputs via a virtual uinput device i created, which X auto recognizes and starts uses.

At first I started going crazy because at random times a button press would not go through, then I finally saw this message and realized the cause. Any solutions?
