Bug Description

Whenever I click an application like sound, keyboard layout setting, power,notification, all power options, apps menu (also happens with finger scroll) etc. However, increasing volume, typing out app name and selecting wifi network does not result in any reset. What is the problem here?

You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

I know that X error from some race-conditions or access of gtk ressources across multiple threads. It might be related to something like that.
