Seems like a bad memory allocation error, possibly in Compiz.

[Daniel van Vugt (vanvugt)]

Compiz does not use glib "g_" functions. That is all Unity.

Ok

Can't be sure if this is the same bug, but when nvidia kernel modules are in use, I get no top or side panels in desktop after I've logged in. Only the mouse cursor over the default wallpaper. Right clicking opens desktop properties window, so some functionality is still left.

With the free xorg nouveau drivers things work ok, but the left panel is grey a little while after I've logged in, but soon turns to normal colour (transparent?)

I've got GeForce GTX 660 Ti (GK104) if that helps out. Also I have pure 64 bit installation and haven't modified or installed anything yet.

How to check if my problem is caused by the same issue? dmesg or what?

Sorry folks, but as part of the bug clean up ahead of 16.04 I'm marking this as invalid because it affects an Ubuntu release which is now unsupported. If you can still recreate this bug in a supported release please do open a new bug and we can triage it for consideration in the 16.04 development cycle.
