Frame blending in time remap producing serious visual artifacts
When the "frame blending" box in the time remap effect is ticked, the rendered output is corrupted.
Some frames of the rendered output are pure white, and some have some blend of white and the video clip frame.
The footage I am producing this from is 4K Slog2 footage from a Sony A7S II. Proxy clips are turned on. Output format is HEVC.
The machine is running Arch Linux and has been recently updated. Kdenlive itself was built from source pulled from git master on 2022-03-22
When the "blend frames" box is unticked, the output video looks normal.
This is the first time I attempt to use this effect, normally I would use Slowmovideo for doing slow motion, as it actually does motion prediction between frames, and can do smooth speeding up and slowing down... all that fanciness comes at the cost of being very CPU intensive and slow.
