Package: virt-manager Version: 1:1.4.0-3 Severity: normal If the remote VM display window is exactly the size it needs to be, then the remote display does not render for me. If I resize the window to be just one pixel bigger (in either or both dimensions), everything works fine. Of course, this totally breaks fullscreen mode if my screen and the remote screen are the same resolution.
This is happening with both a Windows 10 guest, and a text-mode-only Linux guest. In both cases, remote qemu/kvm VMs. The "doesn't render" extends to not even clearing the window background. If the viewer window was partly obscured by another window, and I switch focus to the viewer and raise it, it leaves whatever pixels were on screen from the occluding window still there until I resize the window. Note: this also seems to affect virt-viewer 4.0, but details of that app's behavior make it harder to see what's going on with this bug. The requested run with --debug --no-fork doesn't produce any output when resizing the windows either into or out of the problem state. It prints debug messages for connecting to the remote VM and connecting the spice channels, but once connected, no output on any of the window resizes. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.6.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages virt-manager depends on: ii dconf-gsettings-backend [gsettings-backend] 0.26.0-2 ii gconf2 3.2.6-3 ii gir1.2-gtk-3.0 3.21.5-3 ii gir1.2-gtk-vnc-2.0 0.6.0-1 ii gir1.2-libosinfo-1.0 0.3.1-5 ii gir1.2-libvirt-glib-1.0 0.2.3-2 ii gir1.2-vte-2.91 0.45.90-2 ii librsvg2-common 2.40.16-1 ii python-dbus 1.2.4-1 ii python-gi 3.22.0-1 ii python-gi-cairo 3.22.0-1 ii python-libvirt 2.2.0-1 ii python-requests 2.11.1-1 pn python2.7:any <none> pn python:any <none> ii virtinst 1:1.4.0-3 Versions of packages virt-manager recommends: ii gir1.2-spice-client-gtk-3.0 0.32-1 ii gnome-icon-theme 3.12.0-2 ii libvirt-daemon-system 2.2.0-1 Versions of packages virt-manager suggests: ii gnome-keyring 3.20.0-3 ii python-gnomekeyring 2.32.0+dfsg-3 pn python-guestfs <none> ii ssh-askpass-fullscreen [ssh-askpass] 0.3-3.1 ii virt-viewer 4.0-1 -- no debconf information
