I have a same problem. I think Mintty loses the last output line that ends with 
colored texts.

The left of attached screenshot is cmd.exe and right is Mintty. Mintty loses 
red "Aborted due to warning" line.

Cannot reproduce this issue. Would you provide a test program rather than a 
video?

hmm, it happens randomly, I cannot imagine how to create guaranteed testsuite

today (2014-06-13) I have updated my cygwin and mingw/msys and checked it again
I run this command 30 times
in cmd console
  C:\MinGW\msys\1.0\bin\mintty.exe -h always -p 600,200 C:\Perl\bin\perl.exe -e "print join ' ', 1..100"
perl prints out numbers from 1 to 100
but mintty stops the output at different positions
sometimes it shows complete string
but mostly or nothing or partially:
-mintty 1.0.3 from the mingw installation (mingw itself is up to date but their 
mintty is still old):
  0 62 0 0 0 0 0 0 100 0 100 0 100 71 0 0 0 12 75 0 0 2 0 0 0 19 0 0 100 0
-mintty 1.1.3 just downloaded 
https://mintty.googlecode.com/files/mintty-1.1.3-msys.zip
  0 0 50 100 0 0 0 31 0 0 0 0 0 0 0 0 100 0 0 0 0 100 0 22 0 0 0 0 0 0

and by the way I thought to check cygwin's mintty
and it turned out that it works fine
-cygwin's mintty 1.1.3
  mintty -h always -p 600,200 /cygdrive/c/Perl/bin/perl.exe -e "print join ' ', 1..100"
  10 attempts by turn - all ok - 100 - complete output
so
the bug is only in mingw's mintty

...
ah, one more thing - this time Windows 7 64
