Hi again,
after installing Lyx2.2 (which under the hood again installes inkscape) i get my error again. (First i tried using lyx, then i opened the emf using lyx.) As if inkscape just switched to a different state...

I'll attach some screen shots.... Can i somehow help to track down this?
regards, steffen

For those, who don't know, Lyx is kind of syntactic sugar on top of latex, easing a lot of stuff as for instance image format management. Under the hood for each latex run lyx uses image converters to convert arbitary formats to something latex can handle (e.g. pdf or eps).

If exporting something from a single powerpoint slide to emf using lyx2.1.4 and metafile2eps, i had to scale the image to something very tiny (5%) to cover the width of a A4-page. Now - using lyx2.2. and inkscape the scaling is way more reasonable for the intuitive user (but i am not sure, if there is something as "correct" here, and if so, what is correct.)

I get the same picture if manually opening the emf in inkscape and then save as pdf. In this case not only bug 2.1. applies (all text is moved to the topleft). Further all text is moved further out, so that only parts of the scrambled text are visible any more AND certain lines (which were still present in 2.1. (opening emf in inkscape) just disappear.
