Mouse disappears

[viproom2]

Hello team,

After upgrading to MacOS Sequoia 15.6.
I can see all 3 displays but only able to see the mouse on the main screen. I'm currently using USBDisplay software to view the 2 external displays.
see below hardware details that may help to diagnose.
Hope to hear from you soon.
Best Regards,
