I used `Loader` as I didn't want loading glyphs to block scrollbar responsiveness. `GridView` reuses delegates, but I don't think it's the `MouseArea` + `Label` constructor that's slow. I think it's the "rendering the emoji glyph" in the GUI draw that is the root cause. The cell spacing code re-renders the glyph (which is a slow process), which is why I removed it. Though I guess we can use `anchor.centerIn`: MouseArea { id: mouse width: emojiView.cellWidth height: emojiView.cellHeight Label { anchor.centerIn: mouse width: emojiView.desiredSize height: emojiView.desiredSize } } ... to keep the cell spacing if that's a requirement. Using `fontSizeMode: Qt.VerticalFit` would make emoji's overflow horizontally. Various "hand + skin tone" emoji's that don't yet have a custom emoji are 2x wider than they are tall.
