Payload menu looks empty in UI

[Senanfurkan]

When I press CTRL+Q in MacOS Catalina 10.15.7, Menu window shows up as blank. When I hover over the mouse on it blindly, I am able to see some payloads but it's not usable

Burp version v2021.5.1

Hi,
Thank you for your feedback. I'll need to output it in the extender to find the origin of the bug.
