[nightly build] randomly the audio thumbnail is not displayed.
i saw a lot of commits about thumbnails, a this is just a "report" on what happens sometimes (probably if i made the same video again.. the thumbnail is showed correctly)
i deleted the Kdenlive before starting Kdenlive... just placed it on english language. i recorderd 10 times the video to expose the issue. (9 times the thumbnail was correct... and probably is not related to the 90 degree rotation... i saw the issue also on landscape clips)
the same project after 2/3 more clips... yZRtRU5hFQ
(no way to updated the thumbnail)
