[platforms/drm] show cursor only when it is enabled

In previous code we used to update/show cursor even when the pointer
device was present, e.g mobile device. Guard it behind the cursor
enabled check.

Comment 2 Plata 2023-02-25 12:08:15 UTC

I have this behavior with 5.27.1.

Comment 3 Plata 2023-02-25 12:09:48 UTC

Note that the cursor disappears after touching the screen again.

Comment 4 Zamundaaa 2024-03-12 14:51:39 UTC

Can confirm, the cursor still wrongly shows after screen rotation

hide cursor spy: don't show the cursor on warps

They're not user interaction, and can happen for example on output configuration changes
