System Information
Operating system: Windows-10-10.0.19042-SP0 64 Bits
Graphics card: GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 462.59

Broken: version: 3.1.0 Alpha, branch: master, commit date: 2021-11-17 02:38, hash: ecad33f214

Short description of error
These things were also reported in: #90415 but not fixed yet. Invalidate cache = restart prefetch frames.

Scene Strips:

3D View object changes in referenced Scene strip need to invalidate cache.
Changing the Post Processing setting in the referenced scene in a scene strip needs to invalidate cache.
Changes in Compositor need to invalidate cache.

Text Strips:

Doesn't update while entering text, but do when changing Wrap Width.

Snap Strips to Current Frame:

Is not caching from the Playhead position. It actually makes prefetch caching stop. And it will only start again if Show Cache is disabled and reenabled.

Modifiers:

Curves doesn't update Preview while dragging curve points, only on release.

Unmute Strips:

Need to invalidate cache.

Btw. caching still needs to work when reverse playing and also needs to keep some frames cached on the left side of the playhead for quick reverse playing. There might be an old report open for this, but I can't remember.

These items don't have interface to allow for strip cache invalidation, so I will classify as known issue.

Prefetching has nothing to do with cache invalidation though, In case of snapping strips this probably needs viewport update. Unmute strips does invalidate cache as well, not sure what issue there is.

@iss For checking work done in the linked-to scene, maybe the undo stack can be checked and be used to invalidate the cache if the liked-to-scene is the same scene as the one with work done in?
