Some apps resize and move around, when child windows are dragged.

[Budhajeewa]

How to reproduce the symptom:

#Nautilus (Maximized)

Steps:

1. Open nautilus.
2. Maximize it.
3. Open "Preference" dialog box.
4. Drag it.

Observe:

Nautilus' window becomes small and moves with the "Preference" dialog box.

#Nautilus (Un-maximized)

1. Open nautilus.
2. Un-maximize it, or keep it un-maximized.
3. Open "Preference" dialog box.
4. Drag it.

Observe:

Nautilus' window keeps the size, but moves with the "Preference" dialog box.

#gnome-terminal and gnome-mines

The same thing happens with these two as well. This could well happen with any other application as well; these are just a two of the three that I happened to test.

Any way to mark this as a bug in Artful daily builds?

I don't see a way to do that by myself. I asked about it from @ubuntu on Twitter ( https://twitter.com/budhajeewa/status/903812337186066433 ) , no reply so far.
