Gazebo, gzclient, pins the CPU. We don't see this when using ssh -X, e.g., from a Mac with XQuartz, nor Windows with MobaXterm.

We see this in /var/log/messages:

Sep 22 09:30:11 us dbus-broker-launch[522115]: Activation request for 'org.a11y.atspi.Registry' failed.

And from launching with verbose option:

[Wrn] [GuiIface.cc:119] X server does not support XInput 2
[Wrn] [GuiIface.cc:119] QXcbConnection: XCB error: 1 (BadRequest), sequence: 168, resource id: 158, major code: 130 (Unknown), minor code: 47

Is this a Gazebo issue?
