The Problem: The task manager dropdown menus are all transparent and not readable at all. The same goes for all the dropdown menus of libre office. I have tried to change the desktop theme but the transparency kept on appearing on all those menus hindering me from reading them. Disabling all the effects of the desktop (ALT + Shift + F12) did not help at all as well.
Objective: I need to remove all the opacity and transparency of those menus. I simply need a clear readable desktop environment.
Any suggestions, comments or solutions will be greatly appreciated.
Note: I am using Kubuntu 15.10 (Not a fresh installation. I have just installed the KDE desktop environment on top of the Ubuntu Mate 15.10 then decided to use it as my default.

seems to be darkestIn my case it was the Application Colour Scheme in: Settings -> Appearance -> Colour.
Change the Theme with a Darker one and see how it goes. My menus were white and my theme dark so no menus were visible when I click on a drop-down menu.
