stale cursor images

I'm resending this bug report as a previous one (sent via Emacs)
apparently did not get through. Sorry if anyone sees this report twice.

The problem looks like this:
If a part of emacs window (frame) is obscured by another (non-emacs)
window so that the emacs cursor is still visible, then raising emacs window
via a mouse click (on the visible part of text) results in the following:

1) emacs refreshes previously obscured part of the window
2) moves cursor to the location of the click
3) BUT it leaves the old cursor image at its current location resulting in
two cursor images

Doing it more than once results in multiple cursor images
which is quite annoying

Other notes:

0) Here is what Emacs reports about itself
GNU Emacs 21.2.1 (i386-redhat-linux-gnu, X toolkit, Xaw3d scroll bars) of
2002-04-08 on porky.devel.redhat.com

But a similar problem exists in 21.3 as well

The problem did not exist in 20.x versions

1) I'm using fvwm2 as a window manager, but the same problem happens under

2) The bug is not 100% reproducible (in some cases emacs does erase the
old cursor image). You may need to try several cursor locations relative
to the obscuring window (locations above and below obscurining window seem
to be the most troublesome)
