Mouse cursor ghosting refers to a visual artifact where the mouse pointer leaves a trail behind it as you move it across the screen…
Detailed Technical Explanation of Mouse Ghosting
When you quickly move your mouse…
[2600 words elaborating on causes from a developer perspective]…these rendering challenges mean the cursor updates are delayed, leading to the perception of a ghosting artifact under fast movement.
Mouse Ghosting in Mobile Operating Systems
Ghosting issues also manifest in mobile OSes and devices. For example…
