I can confirm that this bug in libgtk-3-0 still affects gnome-boxes 3.22.0-1 from latest sid. (Tested with libgtk-3-0 3.21.6-1 .) Downgrading libgtk-3-0 from 3.21.6-1 to 3.20.9-1 allows gnome-boxes to render correctly again. You might be able to reproduce this problem if you run the QXL graphics driver (xserver-xorg-video-qxl) in the guest, and potentially the guest agent as well. I can reliably reproduce this with a Windows VM running the QXL driver and guest agent. - Josh Triplett
