Normally if you run this command
printf '\ec'
it will clear the screen and scrollback buffer
http://stackoverflow.com/a/5367075
However using this snapshot
http://cygwin.com/snapshots/x86_64/cygwin1-20140128.dll.xz
it now only clears the screen

20140128 seems to work on my system.
printf '\ec' clear everything and the
scroll bar disappears
so what about a full:

Yeah it works with "mintty", but not with "Cygwin.bat"

1) there is not anymore a cygwin.bat
http://cygwin.com/cgi-bin2/package-grep.cgi?grep=Cygwin.bat&arch=x86
2) mintty is always better them CMD. IMHO

This is, of course, right, but...

...is only your opinion...
@Steven, there was changes to console buffer handling, this is probably a
side-effect of them.

Actually, while you will not find it in any package
search, and it is no longer a Start Menu item,
"Cygwin.bat" is still created in the root (/) of the
installation directory by setup*.exe. Specifically,
via the routines included in desktop.cc of setup's source.
Perhaps this leads to some of the confusion or
expectations with regard to its acceptable use.
Kind regards,
Ken

I shouldnt have to use "mintty" just to get back functionality that has existed
with Cygwin Bash itself for years, not to mention even the most basic Linux
Terminals.

You're comparing apples and oranges.
mintty is a "basic Linux terminal", native NT console is... meh...

Hey Andrey, if you have nothing constructive to add you should consider to stop
emailing. Saying "meh..." is not adding to the conversation.
The fact is that bash.exe by itself has allowed you to control the scrollback
buffer for years. Saying that I should upgrade to mintty because bash.exe is
broken is not a solution, it is a workaround.

looking at the timing, it is possible that the regression
is coming from this change
http://cygwin.com/ml/cygwin-cvs/2014-q1/msg00000.html
I am not an expert in this area but on
https://sourceware.org/cgi-bin/cvsweb.cgi/src/winsup/cygwin/fhandler_console.cc.diff?cvsroot=src&r1=1.283&r2=1.284
Is see that a specific workaround was disabled
--------------------------------------------------------------
+#if 0 /* CGF: 2014-01-04 Assuming that we don't need this anymore */
/* ScrollConsoleScreenBuffer on Windows 95 is buggy - when scroll
distance
* is more than half of screen, filling doesn't work as expected */
--------------------------------------------------------------
re-enabling it and testing should be easy, could you make by yourself ?
Marco

It looks like Chris fixed it already, just decided not to tell anyone. Sneaky
