Openbox (XOrg) Memory Leak in Ubuntu 12.04

[Romith Jinwardana]

Software versions:
------------------------------------------------
Ubuntu 12.04.2 LTS
openbox:
  Installed: 3.5.0-2ubuntu2.1~ppa1
  Candidate: 3.5.0-2ubuntu2.1~ppa1
  Version table:

Expected XOrg to release memory or not to increase memory abnormally when continuously taps.

Instead, XOrg increase resident memory continuously when taps on the screen.

Steps to Reproduce
---------------------------------
Just tap continously on touchscreen inside application opened within openbox. (In my case I just tapped in terminal)

Further details
-------------------------------
It was observed that XOrg has consumed a large portion of memory towards the later part of the day.

Further analysis found that, memory consumption increases only when I use touchscreen, not when I use my mouse.

So, I monitored XOrg memory by continuously tapping the touchscreen and found that each touch contributes to increase in XOrg memory.

Next, I switched back to Unity and XOrg memory usage was normal with both mouse, and touchscreen. So I suspect openbox contributes to memory leak.

Tried different other combinations such as different touch driver versions, and non seems to contribute to memory leak other than openbox.
