At least the Invert parameter doesn't seem to hold its setting, but instead it takes on a random check state after clicking away from the effect, then selecting it again. Also, the other parameters seem to behave erratically too, in that the alpha mask sometimes get updated correctly, sometimes not. However, these other parameters at least keep their settings.

The invert parameter should be fine now, but I cannot reproduce the "the other parameters seem to behave erratically too", could you be more specific about what's happenning vs what you'd expect?

Can you please nudge the Kdenlive master ppa for a new build, so I can test? Thank you very much! As for the erratic behavior: what I noticed is that basically only a left-to-middle wipe worked, most of the other combinations of start and end of the wipe resulted in all different kind of wipes that didn't match the UI settings.
Confirming that this bug is correctly fixed. Thank you very much! Moving this BR to resolved-fixed.
