My Ubuntu 16.04 system just locked up out of the blue, I had to hard-reset the machine.

Now that's booted back up, the Unity menubar has turned transparent, and the light shading around each icon on the lanchbar is gone. It definitely should not look like this.

Fsck did run automatically and found nothing seriously wrong with the filesystem, but something must be different to have seriously disrupted the behavior of Unity, right?

Should I question the integrity of my system?
