The Tooltip for graph points remains on the page. Please refer to the below screenshot.
Is this happening simply by moving the cursor within the graph area or when resizing the screen?
This is happening by simply moving the cursor across the graphs on each tab. Maybe you can try to reduce the graph refresh rate to 1 second and try.
I'm unable to reproduce the issue even after modifying the refresh rate to 1 second. I have attached a screen recording to illustrate how it is functioning on my end.
Do you have any thoughts on why the cursor issue might be happening?
