This text is about debugging problems when cleaning with areas.

Put breakpoint into CleanByMask in CoreU onto condition inside cycle,
condition "i > something" or "(BTarget[i] and $ffffff) = yourvalue"...
...or whatever suits the occasion (find relevant info lower).
Watches:
  i
  BMask[i] and $ffffff
  BTarget[i] and $ffffff
  

Follows info on what are the first interesting pixels in pictures.
