Backport Mate 1.24.1 fixes to 20.04?

Hi. Unfortunately 1.24.0 has a big memory leak in wnck-applet from mate-panel. If I don't kill and restart it every several days or so, it grows to 1GB plus of RAM!

It's not really acceptable to leave unfixed in an LTS release. Or force folks to upgrade to groovy. The fix should be backported, or perhaps update the full desktop if it is easier and contains other such important fixes.

Can anyone help?
