If render settings resolution scale had lowered resolution, cached images from render image/animation session could "stay around" and be incorrectly used in the VSE preview area. Two cases I found are fixed here: - Intra-frame cache was not flushed upon actual final resolution change, - "Source images" for effect/scene strips were not removed when requested resolution no longer matches their rendered resolution.

* Cached intermediate images used while rendering one sequencer frame.
|
|
* - For each strip, "preprocessed" (strip source, possibly
|
|
* transformed, with modifiers applied) and "composite" (result of
|
|
* blending this strip with image underneath) images are cached.
|
|
* - Whenever going to a different frame, the cached content of previous
|
|
* frame is cleared.
|
|
* - Primary reason for having this cache at all, is when the whole frame
|
|
* is a complex stack of things, and you want to tweak settings of one
|
|
* of the involved strips. You don't want to be re-calculating all the
|
|
* strips that are "below" your tweaked strip, for better interactivity.
