GNOME Bugzilla – Bug 513476
rounded corners for progress bars are hard to do
Last modified: 2010-12-22 21:18:21 UTC
GtkProgress has a non-transparent back buffer for the progress drawing. As this creates problems for themes when drawing rounded corners it would be nice if the GtkProgress bar would draw directly instead of having this buffer. I have no idea right now if this is even possible API wise (ie. custom GtkProgress subclasses) though. For this bug the same as for #513471 goes. Mozilla has some issues here, and for them one could add a separate workaround between mozilla and engine. (ie. the attach some data to the widget idea I had in mind)
This should be much easier now that GtkProgressBar is a no-window widget
