Comment 37 for bug 540490

The flicker is caused by ui_indicator_update() removing the old indicators before adding new ones, and the way liferea's ui_tray_update() (which calls ui_indicator_update()) works means it happens after updating every feed, I couldn't find a way to hook it after the entire update is complete. I could work around this by first adding new indicators and then removing old ones, but if, as you said, it's better to remove the draw-attention hint, I'll do just that.
