I cannot say QPropertyAnimation is buggy, but i see it allocated once and lifetime is same as panel, read fps are dropped in some summy day :) At same sunny day if you add new panel, animation is great on newly panel with fresh QPropertyAnimation allocated pointer, so let *refresh* the pointer :)

Do you have a link to the Qt bug for QPropertyAnimation?

If add new panel animation is *cool* as is. The perfermonce decrease can be cause due to swap use, or QPropertyAnimation issue, however we (you KDE defs and i *like a user*) wants plasmashell and it's components (like panel) to works *forever*
