It is a bug in tlRender which can be observed in the Sparks* AWSF movie.

Improved in v1.1.6.

If the movie is started stopped the cache is now extended in the back direction, effectively starting from the end of the movie and the threads will read that portion of the cache backwards. This fixes most 2K movie trailers.

Fixed completely for v1.1.6. Reverse playback and reverse seeking is now better than OpenRV on all 4K movies I tried.
8K movies are still an issue though.
