I think Eric is correct here. I checked the Grom file and the buttons
are positioned on half pixels. We need to change the code to get more
reliable results here, but for now it seems easier to adjust FisicaLab.

I haven't had a look at Fisicalab yet, but something which may or may not be
related is the artifacting I get in GSTest/ImageSelection-test. It happens when
moving the sliders to adjust the image size; the image can leave lines as it's
being resized, but the same code works fine on OS X.
The artifacting seems to to come from calling [aView setNeedsDisplayInRect:]
with a non-integral rect. I suspect at some point the rect coordinates are
being floor()'ed, which would be incorrect. If we mark a (possibly
non-integral) region of a view as needing to be redrawn, at some point we'll
need to compute a pixel aligned version that completely encloses the original
rect.

See attached image. I'm using cairo backend.
I tried to reproduce this behaviour with Fisicalab 0.2.1 and current SVN
GNUstep code and failed to get these artefacts. I am using the cairo backend as
well.
Could you please give some more details on how to reproduce this?
