I can't reproduce this.

Can you provide better steps to reproduce that work on a clean profile? Do you drop the item in the blue area, or on the panel, or somewhere else? What does your about:support graphics section look like? Do the effects in the screenshot go away if you minimize and then restore the window?

Does this reproduce in safe mode / with graphics acceleration turned off? Can you inspect the items in the palette, and how are they positioned?

I also don't understand the second screenshot - I assume the sidebar item is being dragged in that screenshot? Or is it permanently stuck there? Again, is this a graphics issue or is the DOM node somehow stuck in no-man's land? (I'm tempted to think the former, but given that I can't reproduce and the steps aren't really clear, I don't know.)

I think this video will help you to understand more clearly.

A bit, but I still can't reproduce. Please answer some of the questions I mentioned in comment #2, especially the ones about whether you see this problem in safe mode / with graphics acceleration disabled, or on a clean profile, and if so, please post your graphics information from our troubleshooting page (help > troubleshooting information).

Going to close this as incomplete given it's gone 3 months without a reply from the reporter and we can't reproduce.
