Which addon is not letting me pick locks?

Alright, got it. ItemTooltipIcon. That's the result I get from /script d(WINDOW_MANAGER:GetMouseOverControl():GetName())

It seems hovering over an item in my inventory fixes it. Maybe it's unrelated but I frequently have to do this to get rid of pricetracker or mastermerchants tooltip numbers that are sometimes left on my screen.
