"Show desktop" shows remains of previous windows not wallpaper

[Springnuts]

Using show desktop should clear all windows away to show clear wallpaper. Instead the ghost images of all previously opened windows are visible.

Graphics ard is NVIDIA GT218 (GForce 210)
Tried changing from X. Org X driver to NVIDIA 331.89 (from 331 prop. tested).
After reboot the addiitonal drivers windows said "Using the recommended driver" - however desktop display was worse: still showing the ghosting of blurred previosu windows, and also flickery.

[Springnuts (simon-springnuts-orangehome)]

Have added xorg edgers ppa repository, and am now using the correct nvidia driver 340.46. (see http://www.binarytides.com/install-nvidia-drivers-ubuntu-14-04/).
Problem persists.
Addition symptom - unchanged - is that when first logging on there is a period of grace during which the windows do clear away properly when closed or minimised - about two or three minutes.

Status changed to 'Confirmed' because the bug affects multiple users.

[Springnuts (simon-springnuts-orangehome)]

OK I tried an earlier version of the nvidia drivers - 304.123. p roblem remains.

I have tried removing the graphics card and reverting to the on board chip. Problem remains.

On borad chip is:

Updated BIOS - no imporvement.
Switched to Gnome - I have my wallpaper back, and no sign of issues so far. So, is it a Unity thing?

[Aaron Planell (aaronplanell)]

I have the same problem. Two weeks with out Linux :(

[Springnuts (simon-springnuts-orangehome)]

The problem is only present in Unity; logging on to Xubuntu there is no sign of it. So I guess it is a Unity issue?

[Springnuts (simon-springnuts-orangehome)]

Appeared in other environments. I have wrapped it in and reinstalled 14.04LTS.
