Thank for explanation.

I also think it is an error.
But I want a workaround.


(Recently I use VxXsrv as Xsever.)
If I use Cygwin/X, the behavior disappear and work as expected gnuplot-qt on Cygwin.
Perhaps all processes being executed in cygwin solves the issue.

After using below, I can use Cygwin/X on WSL.

However, the situation is the same as that in VcXsrv.

For WSL, I have consider something different.

Anyway, thanks for the hint.
