This is pretty odd. Not a known bug, or one that I think we have a had
reported before.
I guess what you are seeing when you say the cursor is 'cropped' is the
X cursor being truncated to fit in the Windows cursor size of
GetSystemMetrics(SM_CXCURSOR) by GetSystemMetrics(SM_CYCURSOR)
The libXcursor checks various things [1] when choosing a cursor size,
falling back to (smallest screen dimension/48), so I guess it's your
large display causing this issue.
I'm not sure about the best way to fix this, but as a workaround for the
moment, you might try setting the XCURSOR_SIZE env var to something
reasonable.
You might like to try this small test program to confirm what's going on:
$ cat cursor.c
#include <X11/Xwindows.h>
#include <X11/Xcursor/Xcursor.h>
int main()
{
Display *dpy = XOpenDisplay(NULL);
int c = XcursorGetDefaultSize(dpy);
printf("XcursorGetDefaultSize = %d\n", c);
printf("GetSystemMetrics(SM_CXCURSOR) = %d\n",
GetSystemMetrics(SM_CXCURSOR));
printf("GetSystemMetrics(SM_CYCURSOR) = %d\n",
GetSystemMetrics(SM_CYCURSOR));
}
$ gcc cursor.c -o cursor -lXcursor -lX11
$ ./cursor
XcursorGetDefaultSize = 22
GetSystemMetrics(SM_CXCURSOR) = 32
GetSystemMetrics(SM_CYCURSOR) = 32
