[Bug 1552764] Re: Eclipse and SWT are very slow/hang on a fresh 16.04 install (gtk3/swt issue)

[luoyang]

I use ubuntu16.04 desktop amd64, install vivado2016.3.
When I run '/opt/Xilinx/SDK/2016.3/eclipse/lnx64.o/eclipse', it appears the following error, and exited.
How can I find the problem according to the info?

Bug description:
  I installed a fresh Ubuntu 16.04 64 bit from nightly build
  (2016-03-02).

  Eclipse Mars.2 (4.5.2) is often very slow / hangs, especially on start
  of actions (searching projects, importing them, search for updates,
  install plugins etc.

  Things I tried:
    * openjdk8 /oracle java 8
    * OS / CS nvidia driver
    * unity / gnome (metacity and compizz)
    * fresh workspace

  jvisualvm  shows that much cpu time is consumed by
  rg.eclipse.swt.internal.gtk.OS._g_main_context_iteration[native] ...
