Problems to visualize molecules

Dear avogadro users,

I’ve been using avogadro since a couple of months ago, it worked perfectly
on the last Ubuntu versions (10.04 and 10.10),
a couple of weeks ago I upgrade to 11.04 and since this I have problems
opening xyz and pdb files, I attached you a
snapshot of the screen and the terminal message:

QStackedLayout::setCurrentWidget: Widget 0x18d3750 not contained in stack
libpng warning: Ignoring attempt to set cHRM RGB triangle with zero area
Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve
property GtkWidget::visited-link-color' of typeGdkColor’ from rc file
value “((GString*) 0x24b22e0)” of type `GString’

All the best,

There are warning messages, but not indicators of errors. I suspect that upgrading has given you a lousy OpenGL driver. These types of artifacts are typical of driver issues on Windows and Linux.
