For a couple of days my Unity in Ubuntu 14.04 has been acting weird.
The icon borders in the launcher have disappeared and the indicators are acting strange as well (blocks instead of arrows). All of this is independent of the icon/GTK/window theme in use.
I already reset Unity using this tutorial, but to no avail.
Here is a picture of what is happening:
I have honestly no idea what might be causing this. The only thing I know is that it happened a few days ago when I forcefully shut down my laptop after a failed file transfer that had absolutely nothing to do with Unity or the OS itself.
