Effectively, if your 3rd party app defines a custom pixmap cursor whose
ID is not a constant, you cannot retrieve it.
Or perhaps if you test this cursor comparing it with all constant values
enumerated in cursorfont.h, if it does not correspond with any of these,
it could be your 3rd party app window.
Sorry, but I can't help you more.

The whole point is a random 3rd party app makes a custom pixmap
cursor, and I was wondering if there is a call to retrieve
the cursor the 3rd party window I have no control over has defined.
With the intention to get the XImage backing it
and copy the pixels.

Don't you know the ID of your custom pixmap cursors ?
If you do, you can add them to the cases of the switch.

Yea but this does not work with custom pixmap cursors that are
not part of the system cursor theme.

In fact, cursor id are defined in cursorfont.h like
XC_top_left_corner, XC_double_arrow,...

You can write a function which uses XTestCompareCursor in a
switch which tests known cursor id (top_left_corner,
h_double_arrow,...)|

Yea but this only returns true/false it does not return the
cursor_id.

Hello,
Perhaps you should look at XTest extension :

See |XTestCompareCursor function

So XSetWindowAttributes allows you to set the cursor
on the window, basically this is the hardware cursor
when your mouse enters the window that is displayed.
Is there a way to readback this value from an existing
window? Or perhaps another workaround to get the
cursor on a specific window?
I am aware there is XFixesSelectCursorInput but this
listens for changes and grabs the current system
cursor; not on a per window basis.
