[libvirt-users] Issue with virsh screenshot

Hello lists, I have strange issue while creating VM screenshots. virsh screenshot vmname produces ppm image. But when i try to make second screenshot, it produces the same image, even is VM screen has changed. Running screenshot on third time, it produces correct image. It looks like screenshot is producing last image every second time it is ran. OS debian stretch.  virsh --version 2.0.0 qemu-system-x86_64 --version QEMU emulator version 2.6.0 (Debian 1:2.6+dfsg-3), Copyright (c) 2003- 2008 Fabrice Bellard
