Are you remembering to set GNUPLOT_DRIVER_DIR to the appropriate
directory when testing new/old versions?  Mixing different versions
of gnuplot and gnuplot_x11 will yield poorly-defined behaviour.

For a long time the behavior has been that x11.trm didn't know
anything about dashes, while gnuplot_x11 would use dashes if they
were provided as X resources and solid lines otherwise.
I have added an explicit toggle for solid/dashed to x11.trm,
just as other drivers like post.trm and emf.trm have.  The default
state of the toggle is "solid", which is what you always had before
unless you loaded dashed line descriptions into the X resources
database. So...

Before:
    - Default was dashed lines, but only if they are in Xresources
    - No Xresources file unless you created your own
    -> result was default to solid
Now:
    - Default is solid lines
    - Xresources file defines the dash patterns
    -> result is default to solid

No

The axis line is supposed to be an exception (dotted even when the
other line types are solid).  It is possible that there is a bug in
that it gets disabled along with the other dash types. I'll check.
