When clicking the button for "Use color gradient picker" my cursor turns to the eye dropper as expected, however as soon as I attempt to move my cursor it shoots toward the bottom right corner of my screen and it can't be retrieved.
I know to press ESC to cancel the operation so at least it is recoverable.
I am using a single screen fairly new powerful laptop.
Video attached, please ignore the pointer cursor that remains over the "Use color gradient picker" once I've clicked, that's a side effect of my video capture software.
