Description Kamil Páral 2016-09-12 11:56:00 UTC
Description of problem:
Since gtk3-3.21.5-1.fc25.x86_64 virt-manager windows grow with each start. You can see it at:

This has been reported against gtk:
and determined as an application bug:

Quoting how to fix this:


Querying the window size and then setting it with GtkWindow API is perfectly fine.

Querying the window size with GtkWidget API and then setting it with GtkWindow API, *or* querying the window size with GtkWindow API and then setting it with GtkWidget API, is *not* okay, and only worked up until now with server-side decorations only on X11.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. start and close virt-manager repeatedly, it will grow each time

Additional info:
I see the problem not just with main virt-manager window, but also with a VM window (it's taller than it should be, even if you use "resize to VM" from menu).
