The only thing that comes to mind is DESQview/X, and IIRC, that required a minimum of a

There was plenty more than DESQview/X, and there were X11 servers that ran on 286.
There was PC DECwindows which ran on a 286 system on top of a Rational
Systems DOS extender, and on a 386 or better system on top of a Phar
Lap DOS extender. Those were based on ports of X11R2 - X11R4 source in
the 1988-1989 time frame. By then there was no thought of trying to
fit any sort of implementation in a real mode 8088 system.
