I migrated from Mint 17.3 MATE to Mint 19 MATE and my Ctrl+Alt+Shift keyboard shortcuts stopped working.
If I try to enter a Ctrl+Alt+Shift shortcut in mate-keybinding-properties
, the Alt doesn't register
For example: If I press Ctrl+Alt+Shift+X, it registers as Ctrl+Shift+X.
Is there a way to fix it?

This is an Xorg bug and as I understand it manifests itself by Xorg giving preference to shorter shortcuts before more complex ones that include the same keys as a subset.
There is a patch in the Freedesktop bugzilla ticket and you can install it using the commands below (documented already in this Cinnamon issue on Github):
