1Password mini background occasionally gets darker

I have a light menubar, not the dark one, but occasionally, when I open 1pw mini, the background is darker than normal, making some text difficult to read (see attachment)

Steps to reproduce

1. Use 1Password mini a lot. (via ⌘+⌥+)

Expected

The background color would be consistant

Actual

sometimes it's kinda dark.
