Zenny, I reproduced the bug using these effects. For me, Blue Screen alone
does not reproduce the problem. The fix for now is to add these two lines
to /usr/share/mlt/frei0r/not_thread_safe.txt (adjust for where the MLT that
Kdenlive is using):
keyspillm0pup
alpha0ps
You can easily try that without making or getting a new build. Of course,
now there will be much less processing that can not run in parallel, but at
least other parts that do work in parallel will continue to do so.
