This sounds like a different issue, possibly unrelated to
fltk.
When you say 'create and print', what steps are involved?
Are you taking a screenshot with an external tool, or using
fltk's printing support?
What approach are you using to detect 'available memory'?
To identify a memory leak in an app, if using linux, look at
the RSIZE/VSIZE from a 'ps aux' report, or the VIRT/RES fields
in top(1) to see if they're growing,
But if you're looking at the machine's actual available memory,
don't, as that's not a good indicator of leaking so much as
it is just viewing the odd dynamics of disk caching and memory
interaction, which is not useful, as many OS's try to use available
memory for disk caching.
