I thought I would throw this out there - anyone see an issue with cosmos where you click a picklist/dropdown in a screen flow and there is a second or two where the choices go black and then show the list?
We tried opening a case with SF and after a couple of weeks - nothing really came of it - was told to try different browsers and or networks - want to turn it on for our users but not sure we like that behavior - thanks!
@Bill Hare that black beat on a Cosmos screen-flow picklist is the list panel painting before the option text is ready.
The choices aren't missing, and it isn't a bad picklist value. Cosmos draws the dropdown surface dark, then the options land a moment later. Trying another browser once is still worth it, because an extension can make the paint worse. If a clean Chrome profile and Edge both do it, I wouldn't hold the rollout for a flow change.
I don't have a setup toggle that turns that delay off. What I'd send back on the case is a short recording, Cosmos as the theme, and the screen flow picklist, and ask them to treat it as a Lightning styling defect. The flow itself is fine.
