           Summary: wineconsole: alterate screen buffer does not work

          Hardware: x86-64
                OS: Linux

Source code of program to reproduce the issue

Consider the attached program.

On Windows, this program displays the characters '<==>' at the top left corner
of the console. In Wine, if using the curses backend, the program is displayed
as expected (except that the screen attributes are not reset when the program
exits).

However, if using the windowed wineconsole, this program displays just a black
screen. If the source code is modified so that `HANDLE hOut = hInit;`, then the
draw operations do change the screen.

Thank you very much.
