Ok, so I was having an issue and it looks like other people are having this issue as well, where the drop box icon in systrays are either surrounded by a white or black box. Now I am running gnome but it looks like this issue isn't limited to just gnome but kde, xfce and openbox as well.
so it looks like the culprit is the libGL.so.1 that is packaged with dropbox. First thing you need to quit drop box and cd into the the drop box folder in your home folder, then rename the libGL.so.1 and then symlink to the nvidia version of libGL.so.1, then start drop box.
cd ~/.dropbox-dist/dropbox-lnx.x86_64-3.2.9
mv libGL.so.1 libGL.so.1_backup
ln -sf /etc/alternatives/nvidia--libGL.so.1-i386-linux-gnu /home/terroreek/.dropbox-dist/dropbox-lnx.x86_64-3.2.9/libGL.so.1
After starting dropbox the systray icon should look normal, no white or black background;
I can't take the credit found most of it here;
