[Pkg-libvirt-maintainers] Bug#868687: virt-viewer: HiDPI scaling affects rendered image too

[Zoltán Döme]

Package: virt-viewer
Version: 5.0-1
Severity: normal

Dear Maintainer,

GNOME's window scaling for hidpi displays resizes the vm's rendered
image too. With a scaling factor of 2 in gnome if I start with 50% zoom
(virt-viewer -z 50) I get sharp picture, but huge mouse cursor.

Starting with GDK_SCALE=1 env var, the image will not be stretched,
mouse cursor size is normal, but it results in some minimal size
inconsistencies. This means that UI font sizes are as expected, but
buttons are noticably smaller than in other applications.

Seems like virt-manager and gnome-boxes have the same problem.
