Post any defects you find in the released or beta versions of the ImageMagick software here. Include the ImageMagick version, OS, and any command-line required to reproduce the problem. Got a patch for a bug? Post it here.
Not sure if this is a cosmetic issue or a bug. I have observed it in both 6.9.10-44 and 7.0.8-44 on 64-bit Windows 10.
When using "-monitor" with "identify", it seems to omit the last row of pixels from the progress. In my case it seems to read 2013 out of 2014 rows of pixels, as can be seen in the snippet below.
