It is probably mate-specific issue. Try raising the issue on https
://ubuntu-mate.community.

Application switcher (Alt+Tab) is enabled by default under Unity & it is
fine. See: https://i.imgur.com/add9tto.png

It could also be a problem with graphics driver.

Compiz not changing background color is a valid bug though. Does it also
happen gnome-flashback (compiz) session?

Try `compiz --replace` in terminal and toggle set-background-color. What
does the output say?

Title:
  Option to change Application Switcher color/opacity is broken

Status in compiz package in Ubuntu:
  Confirmed
Status in compizconfig-settings-manager package in Ubuntu:
  Confirmed

Bug description:
  Steps to Re-create:

  # Open compizconfig-settings-manager
  # Enable Application switcher plugin
  # In the plugin settings go to the general tab 
  # In the Background section check 'Set background color'
  # and below that specify the desired background color and opacity

  
  Expected: Should change background color and opacity of the application switcher

  Actual: There's absolutely no change, even after restarting compiz

  
  IMO this is a big issue, because the defaults for the application switcher are horrible - it has a highly transparent background by default making window titles hard to read, and because this setting is broken it's impossible to change it

  This also happens with the equivalent setting in the Static
  Application switcher plugin as well

  IMO in addition to fixing this, the default should really be changed
  well to have a more opaque background for the switchers... this is an
  accessibility issue. Take a look at the attached screenshot, this
  looks horrible and the titles are hard to read
