Steps to reproduce:
Open 1Password extension
Same behaviour as recorded there for me.
As a side note, the initial app loading screen needs to be redrawn with different scale for plus! password entry screen etc are ok now though, and correctly sized.
I can confirm the same thing, we'll get this fixed ASAP.
For now, you can work around this by disabling PIN or TouchID. The extension will unlock properly if it ask for master password instead.
