Greetings @w.abd,
To clarify, which Avalonia template are you using?
There are two templates for Avalonia the Framebuffer one and the GTK MVVM one. I believe the framebuffer one does not have a native cursor/pointer implementation at all. While the GTK MVVM one does.
There’s a lengthy discussion about this topic on another thread here: Torizon and Avalonia usb Keyboard and mouse - #8 by eric.tx
Best Regards,
Jeremias
