What happens if you try:
device, true=24, decomposed=1
window, xsize=23000, ysize=3000, retain=2
tv, bindgen(3,23000, 3000), /true
?
On my linux box with nvidia FX 500, the large window repairs
automatically, as it should, when I drag it around or drag other things
on top of it.
If I make the window a LOT larger, say 23000 x 23000, I get a nice error
from IDL saying that there are not enough resources to allocate a pixmap,
which is what IDL uses for backing store when RETAIN=2.
It would be interesting to know how the above code behaves on your machine.
