Admin CP looking distorted

[ErrorCode]

My Admin CP looks pretty distorted after a time-out while rebuilding the caches after trying to install a new theme; nowhere else on the site was affected, though. Anyone know how I can revert this? This is what it looks like (attachment).

Any thoughts? Looks like I spelled example wrong, sorry.

Have you a custom style? Maybe that's it.

Try a hard refresh: Ctrl- F5

I have an iMac.

EDIT: Nevermind, Command + R fixed it. Thanks.

Had this same issue yesterday, never had it before. But yes a hard refresh sorted the problem.
