[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jan C. P. (jan-c-p)]

This could be related to #978626.

This also affects the HUD.

For me this bug does not appear all the time, I have not yet been able to reproduce it or find a work around other than logging out and in again.
