- One of the "documents" has blank client areas (mentioned previously);
these don't ever get drawn.
- Another of the "documents" has a blank pane initially, but
if you diddle around a bit, it does draw.
These sound like a problem I'm seeing with the Adobe SVG plugin, which means that unfortunately I have to go back to Windows during the day. Basically the app doesn't blit its backbuffer in response to WM_PAINT messages in my case, however, forcing it to redraw itself, for instance due to animation, or a mouseover script causing it to change makes it happen.
I keep meaning to look into it, last time I tried I was pretty inexperienced at reading relay traces (well, still am :).
