trunk r29228, branches/1.11 r29229 "GTiff: avoid generated corrupted right-most and bottom-most tiles for 12-bit JPEG-compressed (partial fix that just disable tile filling, #5971)"

Keeping this ticket open since a more involved fix would ideally be needed to replicate last column and last line instead of leaving them to 0.

Awesome. Thanks for the quick preliminary fix.
