Why are my titles squished?

Hey everybody,

Just updated to WP 3.6. I can’t remember this being the case in the most recent version but I find that now all of my titles in the posts section are squished. What it looks like is every word is its own line, down the Title column of the posts section, some words even broken into syllables. Is there any way to expand the titles column somehow? I’d really prefer not to have to dig into my database, or worse, reinstall WP or add extra code to the system.

Thanks
