Setup:
Fusion: 11.0.2
Guest OS: macOS 10.14.2 (18C54)
Host OS: macOS 10.14.2 (18C54)
Issue: in the Host macOS's Accessibility preference pane, when "Cursor size" is set to the maximum (and probably for other settings greater than the default size), clicks often do not hit their targets in Fusion.
I can restore normal selection behavior in Fusion by reducing the cursor size to "Normal."

I suspect that this has probably been a longstanding bug.
Thanks for any confirmation or insight!
