- Pseudo console clears console screen buffer if ESC[?3h or ESC[?3l is sent. However, xterm/vt100 does not clear screen. This cause mismatch between real screen and console screen buffer. Therefore, this patch triggers redraw screen in that situation so that the synchronization is done on the next execution of native app. This solves the problem reported in: https://www.cygwin.com/ml/cygwin-patches/2019-q4/msg00116.html
