Been noticing that sometimes when you have a curve overlayed with the primary OHLC graphics that .paint() is being triggered more then you'd expect with the QGraphicsItem::DeviceCoordinateCache enabled.
This needs some investigation and can be tested on the krakenXBTUSD charts in particular. Enable profiling with chart --profile flag and watch how at some zoom levels the VWAP curve gets redrawn on every cursor move.
