It turns out that the gtk-qt-engine theme has problems with gtk_paint_shadow. The documentation is that it draws around a box, but that engine fills the area completely, painting over anything already there.
I added a work-around to draw the colors on top of the shadow. This will be ugly with some Qt themes, but at least it will get the colors visible. ** Changed in: inkscape Status: Confirmed => In Progress ** Changed in: inkscape Status: In Progress => Fix Released -- no pics for color sliders in Inkscape https://bugs.launchpad.net/bugs/281809 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
