Thanks Daniel, you marked it as regression, could you give details on when/in what serie|version it regressed? Does it impact disco(-proposed) only or something we need to be careful about with our ongoing SRUs?

[Daniel van Vugt (vanvugt)]

The regression occurred in disco-proposed, specifically in upstream release 3.31.90.

(3.31.4 doesn't contain the bug)

[Daniel van Vugt (vanvugt)]

Looks like (from upstream) fixes are required in mutter as well as gnome-shell:

In the help about zoom should also be noted that Super+Alt+8 can be used to zoom
