Created attachment 821141 [details] Debug info of virt-viewer Description virt-viewer can not change the resolution higher than physical size in windowed mode Version: Host: libvirt-1.1.1-11.el7.x86_64 virt-viewer-0.5.7-2.el7.x86_64 spice-gtk-0.20-6.el7.x86_64 spice-vdagent-0.14.0-5.el7.x86_64 spice-gtk3-0.20-6.el7.x86_64 spice-server-0.12.4-3.el7.x86_64 spice-glib-0.20-6.el7.x86_64 Guest:rhel6.5 spice-vdagent-0.14.0-2.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1.Prepare a spice guest,install spice-vdagent,start spice-vdagentd service. 2.# virt-viewer guest 3.Change the resolution from guest,it can change resolution lower than physical size,but fail to set as higher than physical size in windowed mode. first resolution:1024*768 A.change resolution to 1280*720,failed,back to 1272*720. B.change resolution to 1360*768,failed,back to 1272*768. C.change resolution to 960*640,success. Actual results： As description. Expected results: virt-viewer can change the resolution higher than physical size in windowed mode Additional info: 1.The issue can not be reproduced on rhel6. 2.The issue can not be reproduced on full-screen. 3.Attached spice-debug info.
I can reproduce the bug with the following packages: On host: # rpm -qa libvirt virt-viewer spice-gtk spice-vdagent spice-gtk3 spice-server spice-glib virt-viewer-0.5.7-1.el7.x86_64 spice-glib-0.20-6.el7.x86_64 spice-vdagent-0.14.0-5.el7.x86_64 spice-gtk3-0.20-6.el7.x86_64 spice-gtk-0.20-6.el7.x86_64 spice-server-0.12.4-3.el7.x86_64 libvirt-1.1.1-12.el7.x86_64 On guest: rhel6.5 spice-vdagent-0.14.0-2.el6.x86_64
This is by design, there is code in virt-viewer to resize the display to fit the native client resolution while keeping aspect-ratio in window mode.
