Audio thumbnail on mono tracks not displaying properly
The thumbnails on mono audio tracks do not match up with the audio in the track.
Also, when trimming from the front of the track, the thumbnail looks like it's scaling rather than being trimmed.
As a little experiment, I took a mono track that had this issue, and turned it into a stereo track by duplicating the audio on the next channel, and saved in the same format. When displaying in Kdenlive, the issue went away.
