I'm using the windows console with grey background and black foreground for ages. Apart from bugs we had in the past, this setting always worked as expected, except in some border cases. What's important is that you start your shell from a shortcut with these console settings. I.e., you have to change the settings in the shortcut properties. Otherwise, if you start the shell with default grey on black and just switch the color settings on the fly for this console, there will always be artifacts. Somehow the legacy console doesn't like switching colors during a session that much. > > You can confirm what > > happens if xterm mode is disabled by reverting cygwin to 3.0.7. I simply set has_con_24bit_colors to false and rebuilt the DLL. With this enforced cygwin term setting, my vim example works fine, just as /bin/echo -e '\033[H\033[5L' > > If you type 'aaa' in shell prompt and hit backspace, then > > whole line after cursor gets black.
