I'm not completely sure what you mean by "the backtrace of function
<...>", but I assume you want to get the backtrace at the point where
the function is called.
`M-x debug-on-entry RET handle-switch-frame RET` should do just that.
But I think you'll be very disappointed with the result: this is
a function bound to an event, and these are decoupled from the code that
generates/triggers the event by a buffer (this is the buffer that's used
to remember the keys you pressed while a long-running command is still
ongoing).
So the backtrace will likely tell you very little and specifically it
will not tell you the cause of the unexpected frame switch event.
