This was apparently equally a problem in Linux Mint MATE. For a discussion and workaround see: https://forums.linuxmint.com/viewtopic.php?t=169308 and https://ubuntu-mate.community/t/bottom-panel-problems-with-compiz-ubuntu-mate-16-04-solved/6091/5
Here it is suggested that it was solved in Linux Mint 17.1 (without saying how) - could the fix be copied to Ubuntu MATE: https://github.com/mate-desktop/mate-panel/issues/249 ** Bug watch added: github.com/mate-desktop/mate-panel/issues #249 https://github.com/mate-desktop/mate-panel/issues/249 -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1579421 Title: MATE Panel (inc.
