GNOME Bugzilla – Bug 633032
Tooltip not always shown
Last modified: 2012-11-26 13:54:29 UTC
When I put the mouse over an icon in the top panel, it doesn't show the tooltip immediately : I have to move the mouse of 1 pixel to have the tooltip. It is quite hard to explain, but it is very easy to reproduce : - put the mouse _under_ a gnome-panel icon (firefox for example) - move quickly the mouse vertically to put the cursor on the firefox icon: the icon is highlighted, but the tooltip is not shown - move the icon of 1 pixel (keeping the cursor on the icon): it shows the tooltip It is very disturbing when you quickly want to see the tooltip (I have 4 or 5 url shortcuts on my bar), and it doesn't work as expected, it gives an impression "work randomly".
It looks like this bug exists in gtk, rather than in gnome panel. The handler panel_util_query_tooltip_cb in panel_util.c line 1146 is called from gtk.
I can confirm this is happening to me as well. Running Ubuntu 10.10 and Gnome 2.32.0. To get the tooltip to show, you have to hover over the icon, pause, then move the mouse slightly AGAIN, i.e. 1 pixel. Once you have a tooltip shown, you can hover over additional icons and they will be displayed normally without a delay.
I can't reproduce this. Does it happen in any other place on your desktop?
For me, it happens in any program that uses this kind of tooltip. Besides the gnome panel, it happens on the Chromium bookmark toolbar, and the Nautilus navigation toolbar icons. I recorded a screencast (1.2 MB) to show the behavior. NOTE: sometimes the tooltips are "cropped" as shown in the video - I filed it as a separate bug.

So it's not a gnome-panel bug. Could be a gtk+ issue, or an issue with the theme engine.
Maybe related to #516130, but I am not sure.
Just like #636615 this seems to be fixed.
Closing as OBSOLETE for comment #7. Feel free to reopen if this proves to still be an issue.
