ConPTY and terminal graphics
Tue Apr 14 06:48:39 GMT 2020
When the cygwin conpty adaptation is activated for the first time, it
spoils any graphics (e.g. Sixel output) present on the screen. It
probably replays the output code but somehow modified. Test case:
gnuplot -e "splot [x=-3:3] [y=-2:2] sin(x) * cos(y)"
cmd /c ver
If repeated, it does not happen again. Also graphics that are already in
the scrollback buffer are not affected.
(Not a big issue.)
