I'm using 1Password 3.8.22 on OS X 10.11 (El Capitan Beta 2).
When creating or editing a password, all fields looks weird and when I focus on a field and start typing, nothing appears. The initial text is still displayed (weirdly) instead of seeing what I type. So I have to try to type blindly. Then when I focus out to the next field, what I typed appears (often mistyped of course, which gets really frustrating).
Also I noticed that when I try to resize the passwords list column, I get an error dialog titled "NSInvalidArgumentException". See screenshots.
