A work around to this problem is explained in the following link: http://www.iwillfolo.com/how-to-change-gtk-apps-tooltips-text-and-background-color/
The problem seems to be some incompatibility as explained in that page, as per quote below: "When utilizing a desktop environment other than GNOME, or when using a non-default theme in GNOME-shell itself, you may often encounter incompatibilities which are mostly reflected through native GTK apps such as GIMP, Nautilus, Totem, etc…" The solution explained there about modifying file "~/.gtkrc-2.0" worked for me. -- You received this bug notification because you are a member of Edubuntu Bugsquad, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/1515829 Title: Gimp tooltip text color is white on white To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/1515829/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~edubuntu-bugs Post to : edubuntu-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~edubuntu-bugs More help : https://help.launchpad.net/ListHelp
