Details:

Fedora 21 required the environment variable:
export LIBGL_ALWAYS_INDIRECT=1
to be set in order to produce correct print of plots,
using fltk or qt.

Fedora 22 produces plots with NO plot data if
this environment variable is set, both locally and remote.

However, without the variable, plotting and printing
is correct, both locally and through ssh to remote.

This is all for a Fedora 22 system with Intel graphics,
both HD 5000 and HD 6000.

However, now the plots generated for the Manual are all empty
whether the environment variable is set of not!

Since plots work using the generated octave it is not clear
why they fail during the build.  Is an environment variable
set during the plot generation for the Manual?

In any case, this is mainly good news. fltk and qt plotting appears to work
both locally and remotely without any
"special" environment variable.
