Description Anton Gubarkov 2019-05-22 18:51:40 UTC

When I run a VM with virtio or iGVT-g based display and my main display scaling in Gnome is set to anything but 100%, I observe a very unusual Vm display window. Please see the screenshots. My English is not powerful enough to describe what I see in details.
I have a 4K 15" notebook, so 200% is my daily runner. I need jeweler's glasses to read at 100%.
I observe this behavior in virt-manager-2.0.0 and virt-viewer-7.0.
QXL quests display in virt-viewer and are scaled up in virt-manager.
When main display scaling is set to 100% - everything becomes normal.
