Changing theme in Gallery misses frames

[sethladd]

Open Gallery, open drawer, change the theme to dark, then back to light:

When we show a dialogue, which also grays out the background, we also see missed frames. Maybe the same thing?

This still happens.

I'm going to close this in favor of various issue on the Flutter issue tracker, such as https://github.com/flutter/flutter/issues/89127.

However, anecdotally, the experience does seem to be much better today.

Thanks all!
