A while back, I installed Kubuntu 12.10 and switched to the FormaN theme. Today, I completed my upgrade to Raring (13.04) and rebooted. Now all of the graphical controls appear messed up:
I've just finished a complete run of:
sudo apt-get update sudo apt-get dist-upgrade
...so I'm pretty sure everything is up to date.
How do I go about fixing this?
Edit: the problem appears to be with the "air" desktop theme. Switching to another desktop theme seems to resolve the problem - except I prefer the "air" theme.
