Please check if Emacs is in an infinite loop or not, and if
it's in an infinite loop, find in which part of code it's
executing.

It's not likely that the modified function
set_cursor_from_row itself has an infinite loop, but it may
set cursor position to where the other display engine code
don't expect.
