Description François 2021-11-14 13:24:15 UTC 
SUMMARY
When using the Rotoscoping filter, huge system logs are being generated that, in my case, represented more than 10GB of disk space after an hour of usage.


STEPS TO REPRODUCE
1. Add a clip to the timeline
2. Add a Rotoscoping filter to the clip
3. Draw a shaope and move its points around
4. Check journalctl logs


OBSERVED RESULT

Large logs like the following are being generated continuously while dragging a point of the rotoscoping shape. i guess that it also slows down the rotoscoping tool quite a lot.

ADDITIONAL INFORMATION
Comment 1 Julius Künzel 2022-03-20 22:04:56 UTC 
Thanks for your report!

I add the reply from Vincent to your message in the kdenlive mailing list here to make sure the info doesn't get lost:

"""
As a workaround run from command line and pipe outputs to null: `kdenlive >& /dev/null`
Also most packages build with option CMAKE_BUILD_TYPE=RelWithDebSymbols which sadly enable developers debug messages supposed to be turned off choosing Release type: if you build from source that should be the option.
On our side removing that log statement in the code should be obvious, we will try to react not too long.
