Does a Beholder eye ray break its Invisibility?

[Kyutaru]

Let's go to actual dev answers instead of HIWPI.

When a monk uses Empty Body, does the invisibility remain in effect after the monk attacks? Yes. The invisibility of the monk’s Empty Body isn’t ended by the monk attacking.

Does using a bonus action break invisibility from a warlock’s One with Shadows invocation? Taking a bonus action breaks the invisibility of a warlock’s One with Shadows. A bonus action is an action.

If I’m invisible and I become visible when I shoot an arrow at a target, does hiding again require an action? Without a special ability, hiding in combat requires the Hide action.

Take from that what you will. Seems to be that as long as the conditions aren't stated or met that you don't break invisibility. Specific wording matters.
