[Pkg-libvirt-maintainers] Bug#823841: virt-manager: cannot exit fullscreen with the small menu after last upgrade

[Ognyan Kulev]

Package: virt-manager
Version: 1:1.3.2-4
Severity: important

Dear Maintainer,

I just upgraded my Debian stretch/testing and while virt-manager itself wasn't
updated, a new undesired behavior appeared.

I start a VM (another Debian testing but it's not relevant). I enter
fullscreen. Releasing mouse lock with Ctrl-Alt is successful.

Now I expect the small menu in top center to appear but it didn't. This is the
bug.

Fortunately, with mouse released I can do Alt-Tab and thus switch to other
application.

I attach virt-manager.log but there is nothing interesting there. On console,
additionally there are several Gtk warnings:

(virt-manager:10128): Gtk-WARNING **: Drawing a gadget with negative
dimensions. Did you forget to allocate a size? (node box owner
virtManager+autodrawer+AutoDrawer)

My guess is that Gtk or other Gtk-related library got upgraded and this led to
this behavior.

Best regards,
Ognyan
