Previously there was no mechanism to invalidate scene strip cache, when changes were made to scene that the strip renders. Because of this, the cache had to be cleared manually, even for other strips. Strip invalidation is performed from function `ED_render_id_flush_update`. Recalc flags like selection or frame change are ignored as they are unlikely to influence the rendered image. When some ID is changed, all scene strips using `DEGEditorUpdateContext::scene` will be invalidated. Limitations: - Because frame change is ignored, changes to physics caches would not invalidate VSE strips - Only active scene will be invalidated this way. So if an object is linked to 2 scenes, inactive scene cache would be invalid - If animated object is moved, and there is VSE preview to be updated Scene re-rendering in VSE would cause object to snap to its evaluated position. This is because scene frame is changed by VSE. Reported in #139501. To refresh VSE preview after cache is invalidated, relatively big chunk of code was copied from `view3d_main_region_listener` to VSE preview listener. Cases that would not result in visual changes like selection were excluded. Fixes #113137. Pull Request: https://projects.blender.org/blender/blender/pulls/138231
