I'm a little confused. If the fix is not related to cairo, yet the fix
helps only the cairo backend, then that suggests there is an
abstraction problem somewhere in poppler, (eg. two copies of the same
code where there should be one).
Now, if there are backend-specific fixes that help one poppler backend
outpace another, then there's not much that can be done to prevent

I'm certainly not offended. I wouldn't ever encourage someone to
switch to cairo unless there were a quality or performance benefit
they could benefit from, or if there's some other direct cairo
benefit, (eg. instant support for multiple backends or something).
And I know that in many situations, cairo just isn't there yet on the
performance front, (but we're planning to put a lot of effort into
cairo performance particularly over the next month or two).

I wouldn't argue for restricting a fix to the cairo backend if it
applied just as well to the splash backend, (see comment above on the
But I do have to say that I don't understand your reference to gnome
and kde in this context. Has something made made you think that cairo
is more directly associated with gnome than kde? And what can I do to
help change that? That's an impression I certainly don't want anyone
to be left with. I'd like cairo to be usable by any desktop
