I am using Ubuntu 16.04 LTS in Virtual Box.

I am facing the launcher icon resize issue since yesterday. Hence I deleted the VM and installed a new instance. Facing the issue still.

If I run unity it's working for that moment, but doesn't give a permanent solution. Please Help... Thanks in Advance.

Try this command in terminal gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/uni‌​tyshell/ icon-size 20 – Sergiy Kolodyazhnyy Jul 20 '16 at 13:10
    
@Serg It is not working for me. – vjn Jul 20 '16 at 13:29
    
ok, that's means something is really wrong with your Unity shell. GUI option and command line option do the same thing. So here we can rule out problem with the System Settings menu. Can't suggest much more - never seen this happen before. Consider trying to purge and reinstall Unity shell. You can always temporarily switch to another shell, gnome for instance – Sergiy Kolodyazhnyy Jul 20 '16 at 13:35

In VirtualBox 5.1.4 r110228 with the same version of VirtualBox extensions installed in Ubuntu 16.04, enabling 3D Acceleration (Settings... > Display > Screen > Enable 3D Acceleration) fixed the launcher icon resize issue.

Virtual machine settings

Unfortunately, I also had to disable Hardware Acceleration in Google Chrome running in the VM otherwise Chrome just appeared as a black window.

Update 1 In addition to enabling 3D Acceleration, install VirtualBox Guest Additions from the Ubuntu repo instead of inserting the VirtualBox CD image:

apt install virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11

VirtualBox Guest Additions from the Ubuntu repo fixed rendering issues with Chrome and VS Code.

This didn't worked for me. – Rishikesh Darandale Sep 11 '17 at 17:15
    
I need to keep 3d disabled otherwise the mouse disappears (and this is nothing to do with mouse integration - it just vanishes sometimes regardless of that setting). – Dr Eval Sep 17 '17 at 16:35
    
With the same issue, this fix works for me. Thanks. – Brian Erickson Nov 22 '17 at 20:46

I had this problem on suddenly power off & I try almost everything & they didn't work, exept this:

Install "CompizConfig Settings Manager" from Ubuntu software manager & run it

Then click on "Advance search" that locate above close button & search for "launcher" word then click in the Plugin state on "Ubuntu Unity Plugin " then click in the Group state on "Launcher" then scroll down & set 48 to your favorite size, mine is 20 Screenshot
