I cannot reproduce this bug in an up-to-date Disco. OK, I think I discovered something, when I updated mutter in bionic-proposed, it didn't pull the updated version of libmutter-2-0 and gir1.2-mutter-2. So I had a mix of: mutter 3.28.3+git20190124-0ubuntu18.04.1 mutter-common 3.28.3+git20190124-0ubuntu18.04.1 gir1.2-mutter-2 3.28.3-2~ubuntu18.04.2 libmutter-2-0 3.28.3-2~ubuntu18.04.2
Now I cannot reproduce this bug after I manually installed libmutter-2-0 and gir1.2-mutter-2 from bionic-proposed. So I think the problem is mixing old and new versions of mutter packages. This bug could be closed unless there is a need not to.
