Can reproduce; way too slow.

Thia is caused by the use of a Flickable in DesktopBar.qml. It should be a ScrollView with a ListView in it. I tried changing it, but it's pretty fiddly to preserve the existing centering behavior, and I gave up.

Making that change would likely also fix Bug 478968 and Bug 449908.
