[reporting a possible bug, running v2.1.5 on Windows 8]

Setting deinterlace to Discard or Mean suspends (*) the Logo Erase effect.
Switching to other modes or turning deinterlace off, resume logo erasing.

(*) If you look in the Effects panel, Logo Erase still appears on, but you have to turn it off-and-on to actually bring it back to work.

2.2 is out maybe you could try that?

In the meantime I would confirm it's a bug: I later noticed that with deinterlace Discard or Mean, it's not that the mask isn't applied, but doubled in height. In other words: you can see the cloaking acting at x=x but y=y*2 (twice from the top), and again, correct in width but doubled in height.

Mine is merely a guess, but I would attribute it to some global variable that these two specific deinterlace routines needs to modify (height x 2), but that the masking routine still assumes as original. Or something like that.

I tried v2.2 (thanks daaceking) but with no luck.
