Thanks for the clear bug report. Indeed we weren't being very smart here, fixed upstream now:

virt-manager: Only save window dimensions on app exit (bz 1262561)
Rather than on every window change event which spams dconf and hits
the disk repeatedly. The new method is roughly what is suggested by

Created attachment 1072757 [details] video of the problem Description of problem: When moving virt-manager window in Gnome, dconf-service is having ~0.5MB/s write operations. It seems that with every pixel move, width and height gets updated. Version-Release number of selected component (if applicable): 1.2.1 How reproducible: Reproducible on arch linux with gnome. Steps to Reproduce: 1. run 'dconf watch /org/virt-manager/' 2. with the same user that ran command in point 1., start virt-manager 3. move the virt-manager window left-right Actual results: Significant i/o (~0.5MB/s) Expected results: No frequent writes. Additional info: VM do not have to be started.
