Immutable disk mounted to multiple VMs crash on resume saved state

Immutable disk type has changed behavior or is broken. Previously we have used it to lock an OS disk and attach it to multiple VMs (which get their own difference files).
Now when attaching it as immutable to multiple VMs you can't start more than one VM and you get an error about read-only.
Suddenly for no apparent reason it started working with multiple VMs but there's a bug: When resuming saved state the VM freezes with corrupted display. Multi-attach works but sometimes it has the same bug.
