-Y is an authorization hack, but X over ssh already works great (xterm, 
et al work fine).  So it's not that.  I get the same thing the original 
poster gets: apps work fine on the console; graph gets displayed, can't 
manipulate sliders, etc. over SSH.  But: the window does come up; it's 
just like the focus is away from that window.

Under Xvnc, I get this error:

Error: Cairo 1.2.6 does not yet support the requested image format:
       Depth: 8
       Alpha mask: 0x00000000
       Red   mask: 0x00000007
       Green mask: 0x00000038
       Blue  mask: 0x000000c0
Please file an enhancement request (quoting the above) at:
http://bugs.freedesktop.org/enter_bug.cgi?product=cairo
assertion "NOT_REACHED" failed: file "cairo-image-surface.c", line 201, 
function "_cairo_format_from_pixman_format"
Abort trap (core dumped)

So I'm gussing it's different X server implementations that are getting 
screwed up here.
