Hello, for my plots I use an Infinite vertical line to simulate a Cursor. When the cursor is dragged by the user the instantaneous signal values at that timestamp are reported to the user in a different widget.
My issue is that with a large signal count (let's say 4000 signals) moving the cursor triggers a complete repaint that is really slow to execute. Is there some way to have like an overlay where the bottom layer contains the signal curves (and thus dos not require a repaint when the cursor is moved) and the top layer contains the Cursor?
