Mouse Cursor goes beyond visible resolution issue

[Tirupathi Korla]

Hi,
We are running embedded QT on ZynqMP platform.
For Display we are using Display Port controller.
Display Port is configured to enable two layers i.e one is graphics layer (for custom application) and other is video layer(for GUI).

Requirement is to run QT resolution in multiple resolution.
To change the resolution we use drmModeSetCrtc API and we could able the see the resolution change on display. We observed mouse cursor able to go beyond the visible area when the resolution is smaller than actual resolution.
Can someone give me a hint how to set mouse cursor visible resolution.

Thanks
