Dear Maintainer,

Since the rebuild with the wxWidgets GTK 3 package, the wxt terminal
updates only after the window is focused under gnome/wayland.
Here are steps to reproduce:

1/ start gnuplot
2/ set term wxt
3/ plot sin(x)
4/ plot cos(x)

After step 3, the sine curve is plotted in the wxt terminal.
After step 4, nothing happens. The cosine curve appears only after the
wxt window is focused.
This behavior manifest with gnome/wayland but not with gnome/xorg.
The qt and x11 terminal are not affected.
Everything was fine before the rebuild with the wxWidgets GTK 3
package.

The request to rebuild against wxWidgets GTK 3 (#933431) recommends to
also look at bug #900678 (wxwidgets3.0: wxGLCanvas doesn't work with
Wayland). As suggested, I ran gnuplot after setting GDK_BACKEND=x11.
This fixed the issue. The plot window is updated immediately.
