(Toolkit :: Downloads API, defect)

Each time i start a download it takes about 10 seconds for the item to fade in
completely while the cpu is at peak and if i remove another completed item while
it is fading the fadein is restarted and my machine bogs down for 10 more seconds.

Reproducible: Always
Steps to Reproduce:
1.Download any file.
2.Remove any previously downloaded file while the fadin is running.
3.

Actual Results:  
At first my machine goes very slowly while the fadin effect is running.
Then the fadein restarts when i remove the previous file.

Expected Results:  
The fadein should use larger steps to reduce CPU load.
The fadein should not restart when i remove another file from the list.

Try the Download Manager Performance Patch extension?

I installed the patch mentioned in comment #1 and it got better. But the restart
of the fade when removing another item is still there but i should perhaps post
another separate bug about that.

Duplicating against bug 227260, because of the "restart of the fade when
removing another item" comment.
