Created attachment 1221927 [details] screenshot of VM console Description of problem: I have a HiDPI screen (2880x1620) on my notebook. When I run Gnome on wayland, I have no control over the scaling of the virt-viewer. The VM window is always scaled 2x. I used to run my VMs pixel-to-pixel. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Run Gnome on wayland. 2.Start the virt-manager and open the running vm in virt-viewer. 3.Observe the situation like in the attachment. Actual results: the VM screen is scaled 2x. Note the size of the screenshot (2880x1620) vs. the indicated resolution of the VM. Expected results: the VM screen scaling is controlled by the virt-viewer setting Additional info:
When Gnome is run in X session, everything works fine.
upgrading to gtk+-3.22.4 fixes the issue with enourmous UI elements sizes on HiDPI display and also fixes the issue with 2x scaling of the graphical console.
