That is, if I simply add to the bottom of the above code: print "Something is fishy"; The image happily redraws itself. Does anyone have any suggestions on a better way to get this thing to redraw, without needing to output anything? FWIW, outputting text only fixes the problem when I output to STDOUT. Using warn to print to STDERR will not fix it, the image doesn't get redrawn in that case. Any thoughts would be great, thanks!
I suppose your code is inside a callback which doesn't return a value
(and in fact returns false)? After adding the print() statement your
callback now returns true. So probably adding a simple "return 1" at the
end of the subroutine could do the trick.
