CursorUIViewService (Not Responding) – High CPU Usage on macOS

Hello,

I'm experiencing an issue with CursorUIViewService on my Mac. It frequently becomes unresponsive and consumes a high percentage of CPU in Activity Monitor (around 40%). This causes system slowdowns and lag.

Here are the details:

macOS Version: Sequioa 15.3.2 (24D81)

Mac Model: Macbook Pro M4 Max

CursorUIViewService shows "Not Responding" in Activity Monitor.

The issue persists even after restarting.

I've tried force quitting the process, but it restarts automatically. What could be causing this issue, and how can I fix it?

Thanks in advance for your help!

MacBook Pro 16″

For now, I managed to get around it by disabling the redesigned cursor through Terminal.
