When I hover mouse cursor over firefox or amarok in the taskbar, the respective taskbar entries get an urgent window hint (white glow). If I focus and minimize them, the taskbar entry gets back to normal until I hover the mouse over it again. This is extremely annoying. Any help?

Also here is a short video of this bug: http://youtu.be/RZI7V2B6mhA

I had been being annoyed with he same (though I think the apps glowing were diff, one was Opera) but for me it recently stopped and I have no idea why (nor when).

What versionof KDE? Does it happen for all users?

Mine is 4.8.4
And yes - sometimes it just stops happening, then I launch something else or restart, it happens again. Did not determine what causes it exactly.

here's a bug report https://bugs.kde.org/show_bug.cgi?id=275835 and a similar thread viewtopic.php?f=67&t=97043

and this annoyance has reappeared on my desktop
