Comment 11 for bug 1548104

Just a bit of additional information:
The program "gtk-demo" (test program that is part of GTK) is also affected by this issue, so it's not exclusive to Inkscape.

Leaves the question if it is a general issue with GTK that needs to be fixed in GTK code or if it is something we can work around using gtkrc or similar methods.

I'll investigate further and report and upstream bug when I find the time.
