Hi.

I have my own modified  Inkscape icons, and I edit the icons again after layout change in the 'icons.svg' a few years back. But with Inkscape 4,8 I have the ugliest vector program on earth. The 'layer icons' is to big, even if I change back to the original icons svg file. But direct after the installation of  Ubuntu studio, with Inkscape it was honky dory.
Preferences do not change the layer icons, but all other icons in Inkscape.

Inkscape 4.8
Ubuntu studio 64 bit 13.10

Maybe:
I have my own made icon theme, and it have a old "index.theme" file. Should I search for the problem in that file?
