Is there a test script that demonstrates this?
I don't recall ever seeing such a message.

You mean this broke recently?  I must not have been
paying attention.  What broke it?

Do
     splot x with line palette
or
     set pm3d
     splot x

and use mouse to rotate plots.

It has been like this for quite some time after a fix about a year ago where the gplt_x11 palette was changing when more than one x11 window appeared on the screen.

The fix resulted in "allocating colors..." to appear on the x11 title bar (not stdout).

Try

> set pm3d

and then use the mouse to rotate the image.  The sluggish behavior is fixed by the patch...  but hold on a bit, I have to fix the bug that Juergen found.
