VSE Scene Bug when updating scene

Exact steps for others to reproduce the error

open blender
2.Select every object and delete them

I can't really recreate that here, .blend?

Think @Blendify is referring to caching issue here…

Not sure how to solve that though, pretty much any change in a scene may alter its render or not, we cannot invalidate cache on each and every NC_SCENE notification :/

Sergey, Antony, maybe you have idea here?

That works as expected - if you know how it works of course, which is not what the users might expect. The refresh button is there for that reason.

To solve this through notifications we'd basically have to add new notifications in a gazillion places in blender, or we'd have to have a dependency system somehow, but again there are so many places that would invalidate the sequencer.

I am tempted to reject as working as expected, but I'd like some more opinions on this first.

You can't reliably invalidate sequencer cache with just notification system. Some sort of depsgraph is needed for that, but even then it's not totally trivial to avoid unneeded cache freeing.

For now just use manual cache update button.
