[ovirt-users] windows remote-viewer vs. linux vm: strange keyboard problem

Hi all, I have the following strange problem with virt-viewer 5.0 and 6.0 on Windows 10: when I connect to Linux VMs running on a OVirt 4.1 cluster it sometimes is not possible to use e.g. "AltGr + q" to get the "@"-sign or "AltGr+8" for "[" on my german keyboard. It seems to be a problem only when I use a dual screen setup with Linux VMs. It is possible to get it working by just moving the mouse to the top center of the screen until the remote-viewer panel shows up. After this the keyboard works for a short period of time until I work on the other screen. I tested CentOS 7,CentOS 6 and Fedora 26 VMs. Windows 7 VMs do not seem to show this problem, so I'm not sure if it is a problem with virt-/remote-viewer, OVirt/qemu or the Windows 10 client. Does anybody else see this behaviour? What would the best place for a bug report, OVirt and Spice/virt-viewer are separate teams, right? thanks in advance, Uwe
