I had the same problem and traced it down to the xgps backend a few days ago:
It has nothing to do with gmodels. It's a general problem of window drawing
using the xgps backend. The xgps backend doesn't give the X Window system
enough time to finish resizing before it starts drawing to the window. The
problem only shows in Menus because Menus draw a lot of Windows in series.
In xgps/Source/SharedX/XGContextWindow.m,
[XGContextWindow -_updateWindowParameters:]
the window parameters for drawing (especially the width and height) are
updated before X has finished the resizing of the window (started in
-DPSplacewindow:)!
I tried XFlush() and XSync(), but both functions wouldn't wait as expected :-(
I have no clue about X, so what I did (in -_updateWindowParameters:) is get
the window geometry in a loop, until the values actually changed. This works,
but there should be a better solution.
There is another hack in [XGContextWindow DPSplacewindow:] which sends a
resize notification to the NSWindow, in case X wouldn't send a notification.
Maybe this would be the right place to wait for X.
Here is my patch (hack):
*** XGContextWindow.m 2000/05/05 21:15:16 1.60
--- XGContextWindow.m 2000/05/26 18:24:19

XFlush (XDPY);
! XGetGeometry(XDPY, window->ident, &window->root,
&x, &y, &width, &height,
&window->border, &window->depth);
window->xframe.size.width = width;
window->xframe.size.height = height;
