Hi,
Has anyone ever seen this and/or know how to fix it? I'm running CLX
under SBCL and use Blackbox as my window manager. I paint the screen
and everything is fine. However, when I switch to another
screen/workspace and then come back, all my windows are gone except for
the top window.
What makes this really odd, is that I get a visibility-notify event
that allows me to repaint my windows, which I do. I have debug
statements that show the windows are being exposed and drawn. They
just don't show up. I'm sort of at a loss as to what's wrong.

I get a similar sort of behaviour in my fractals code, but the
behaviour is expected because of the way I'm currently doing things (I
basically pause an event processing loop while I display another
window).

Shouldn't you be doing this on :exposure events? That's what I do, at
least, but I'm just learning CLX myself. It seems to work for me, though.

Beware of bugs in the above code;
I have only proved it correct, not tried it.

Hm, maybe the WM unmaps your windows when switching workspaces, so when
you return, you need to see if your window is mapped, is exposed, etc.
