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
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
Significant i/o (~0.5MB/s)
No frequent writes.
VM do not have to be started.
Thanks for the clear bug report. Indeed we weren't being very smart here, fixed upstream now:
