Usually when you have a red dot mark on the UI, it means a notification or something you need to deal immediately. This is such a random icon design. I don't even know what it's supposed to mean.

Me neither...
The Work Light options look good in theory, but after a few hours trying them out the reality is not so successful. A feature that doesn't seem to have been really thought through IMHO.

it doesn't seem completely random to me
in Solaris red dot means Viewport Overrides and choosing Work Lights or No Lights option will ignore the scene lights and therefore is also a viewport override, so my guess would be that's what the red dot could mean

if that's the case there is a bit inconsistency in the notation, as with actual viewport overrides being on on the stage and also turned on under the Sunglasses icon, I'd also expect sunglasses icon to have a red dot to suggest that some other Viewport Overrides are actually in use

Yes, it's a carryover from Solaris. The Material toggle also does the same thing when off. The UX team wanted some sort of indication that WYSI*not*WYG for a couple of very common cases that people kept tripping over when rendering with husk, especially with the physical sky and domelight worklights. It's definitely a bit of a slippery slope change - there's dozens of settings that can change what the viewport shows versus what husk renders - but we decided to start with the main offenders.

So I suppose the red dot simply means "you're not using scene light"...?
