KCMs like Workspace Theme -> Look and Feel have grids with delegates that show tooltips on hover. Those tooltips are incorrectly positioned in all of those KCMs, at an offset to the mouse pointer. They show tooltips like this: Tooltip.showText(parent, Qt.point(parent.mouseX, parent.mouseY), model.display) I'm guessing Qt doesn't correctly map the coordinates to the window due to the embed. This is technically private API we're not supposed to use, so it's tricky ... Reproducible: Always
I can confirm this

This has been fixed in an upcoming Qt release.
