Window controls became invisible

[Vadim Peretokin]

The window controls suddenly became invisible. They still acted as they should.

This happened again.

[Marco Trevisan (Treviño) (3v1n0)]

Mh, never experienced here.

Did you install any custom theme?

[Vadim Peretokin (vperetokin)]

I haven't, no. This happens infrequently but does happen.

[Marco Trevisan (Treviño) (3v1n0)]

Quite weird. Is this happening to all windows or just one?

[Vadim Peretokin (vperetokin)]

This happens to all windows when it does happen.

[Vadim Peretokin (vperetokin)]

I worked out that it happens to a window depending on its position in a dual-monitor setup - attached is a video demonstrating the problem.

[Marco Trevisan (Treviño) (3v1n0)]

Can you please give me the output for
  gsettings get com.ubuntu.user-interface scale-factor
  gsettings get org.gnome.desktop.interface text-scaling-factor
  gsettings get com.canonical.Unity.Interface text-scale-factor

and:
  xrandr
