The icons in xfce4-panel (4.0.5) gets partly displayed. Left and Right side are cropped. This happens when the panel is not set as Large (so with: tiny, small, etc.).
Additional information: Brandnew Gentoo installation, though a problem with the compilation of calendar which failed. Installation done on a Athlon XP. Identical installation on Athlon Thunderbird where everything, including calendar, works fine.
The problem is that gtk changed button size allocation. There is a fix in the CVS version that should be backported soon if it doesn't cause any problems.
Just to confirm this has nothing to do with imlib/libungif not being installed, but just with the fact one system uses gtk+-2.4.1 (working) and the other (new) uses 2.4.3?
yes, as jasper mentioned, this is a known issue with newer releases of gtk 2.4.
Fix is in CVS and will be in the next release.
