On Ubuntu-MATE 16.10, and now with 17.04, I have every day one or two crash of mate-maximus.
Somebody has a solution ?
I found these references on the bug:
But no solution
Sorry, not fixed yet. I think it affects GTK+3 builds of MATE. I still get it myself sometimes.
As a workaround, you can disable Maximus in Startup Applications Preferences, if you don’t need the features it provides.
Obvious ! I don’t need it… Problem solved for me 
Thank you !
What is mate-maximus?
It is a tool that forces all windows to be shown full-screen.
I guess this is mostly useful for low-res displays like those found in netbooks and the like.
There is an option in “Mate Tweak” to automatically maximize newly opened windows? That work?
Yes, though it has a problem with CSD windows.
The crash mentioned in the first post should be fixed now in 17.10. Would be nice to have it backported too, but that's up to @Wimpy...
