Nexus 7 2013 Performance Drop

[wortwortwort]

My Nexus 7 2013 (Android 4.4.2, unlocked bootloader but not currently rooted) suddenly started to have very poor graphics performance. I closed open apps to free up additional RAM, but that didn't help at all. I tried restarting the tablet but the problem persists.

Does anyone have any suggestions or should I just back up my data and then wipe everything (and root it again while I'm at it)?

I decided to just reset everything.

Edit: Whatever the problem was, it's gone after resetting.
