Hi, With gtk+ 2.21, the panel notification area doesn't work correctly: each notification icon appears at the center of the screen instead, in its own small window, continuously flashing/flickering (they continuously appear and disappear from window list, thus 100% cpu…). I don't know if it's regression in gtk+, or (as for ExoTreeView a few weeks ago) a "new behavior and we don't care if we broke something, gnome works fine", or a bug in the panel… If you think it's not a bug in the panel, I'll file a bug against gtk+. Thanks! xfce4-panel: 4.6.4 gtk+: 2.21.[01] (works fine with gtk+ 2.20.x)
Looks like it. Will try it too when I'm home.
Mmmh, I'm not sure, but I think ubuntu activated (or patched) the "client side window decoration" stuff in gtk 2.21. Maybe that's the cause of the bug.
It seems it's related to that (and rgba support). If I start the panel with XLIB_SKIP_ARGB_VISUALS=1, it works fine.
Yeah that is a possibility too, the tray can't embed rgba in a rgb window, this is fixed in 4.8, but won't make it into 4.6, since it requires a lot of code changes.
