      https://bugreports.qt.io/browse/QTBUG-68609 causes massive increase in TIFF file size.

      The result of this change is that instead of packing the whole file in 1 big block it's now compressed in small strips (2 lines in my example) which completely ruins LZW compression.

      The result is that the file size increases from 238k -> 370k.

      Please re-open this bug and use a more suitable strip size.
