Bug ID: 447155
Summary: Audio thumbnails show double impulses after reloading
project
Product: kdenlive
Version: 21.08.3
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: kde...@neofin.net
Target Milestone: ---

Simple click track for repro
My audio thumbnails get corrupted every time I reload my project. It's
particularly visible on my current project where I'm using a click track to
help with AV sync.
STEPS TO REPRODUCE
1. Generate a click track in Audacity (I'll attach a sample)
2. New project, add the audio clip
3. Save project
4. File > Revert, or restart kdenlinve and open the project
OBSERVED RESULT
Double impulses on the waveform displayed in the clip monitor, and on timeline
audio thumbnails. The audio is actually synced to the second impulse; the
first one is a lie.

EXPECTED RESULT
Single impulses on clip monitor / timeline thumbnails.

SOFTWARE/OS VERSIONS
Debian 10.11 "buster"
kdenlive-21.08.3-x86_64.appimage
kdenlive-22.03.70-8b0a5ea-x86_64.appimage
ADDITIONAL INFORMATION
Workaround: delete the audio thumbnail cache and restart. Thumbnails are
correct the first time the project is loaded. After the next load they are
wrong again.
Resetting to the default configuration does not solve the problem.
The same problem occurs with or without ffmpeg thumbnails enabled.
