Select widget content not appearing in overlay #5161

Open darrenburns opened 1 month ago

darrenburns commented 1 month ago

Some times when I open the Select dropdown using the keyboard, the content in the dropdown is not visible, it's just an empty box. It's still functional, but nothing is visible.

I'm not sure the conditions to replicate consistently yet - I think it's happening in apps with a lot of widget. Maybe a race condition.

I can't seem to reproduce this, even with a metric tonne of other widgets.

I wonder if it's relating to the content inside the dropdown. Maybe each line is wrapping and so appears invisible. I'll keep my eyes peeled for clues 🕵️‍♂️

I did notice that sometimes when the drop down is made visible, there is a frame where the contents are blank, before being filled in.

That puzzles me, because it should all happen in a single update. Seems plausible it is related to the content or wrapping...
