Window shrinks and menu disappears when other app is opened/closed to the dock

[Neil McPhail]

Ubuntu mate 20.04 running on a ThinkPad X230 (intel graphics) at 1366x768 resolution using the "Redmond" layout.

Steps to reproduce:

- Open Mate Terminal in standard 80x24 window
- (My font is set to Monospace Regular 10 with "show menu" ticked)
- run `for i in {1..23}; do echo $i; done`
- Open Telegram (I have the non-snap version installed)
- Repeatedly close (using the X button) and re-open Telegram from the dock so it maximises/minimises
- Watch the terminal window as you do this

What should happen:

- terminal window should not be affected beyond gaining/losing focus

What actually happens:

- Menu bar in terminal window disappears and reappears. Terminal window shrinks and lines are lost from the top of the terminal

I think this might be a marco bug. It happens with and without compositing. I wonder if it is related to the switching of focus?

Here's a little video clip. I've logged out of telegram for privacy reasons (and it doesn't minimise to the dock when logged out) but you can see the effect just by opening the app.

This was fixed via marco 1.26.0-0ubuntu1 which was introduced in Ubuntu MATE 21.10
