Re: Redisplay problems?

[James Cloos]

I've seen the lost cursor, too.  But cannot reliably reproduce.

It seems to occur more often if, when gnus is starting up, I switch back
to the workspace which includes the emacs frame too many times.

That is, if emacs gets a lot of these sorts of events while waiting for
something like gnus to finish running:

(Generated here by running xev(1) and switching workspaces from and to.
These are therefore the events my window manager sends when switching
workspaces.)

The other symptom is that eventually nothing displays in the frame.

But I cannot duplicate it at will, and I hadn't even confirmed whether
it is an emacs bug or a xlib or xserver bug.  (My xorg is all git master.)

I use --with-x-toolkit=lucid --with-xaw3d.
