I am getting this error code using ovserver

1.1.4-SNAPSHOT-2019-01-16_07:30/Windows10.0/Java8(64)1.8.0_201-b09

I have some observe operation like following:

rp = SOME REGION

r1 = some region
def pcheck(event):
    global rp
    print "in pcheck"
    r = Some region
    ppp = some pattern (png file)
    r.wait(ppp,60)
    rp.stopObserver()

def something_changed():
    try:
        r1.wait(some picture, 60)
        rp.onChange(50,pcheck)
        rp.observeInBackground()
    except:
        pass

def main():

     ......
     something_changed()
     #some where in the main code I call this function (something_changed) to start monitoring for the change and I hope it gets triggered once certain conditions are met:

main()

and I get this in the log:

LOG:
[error] Region(108295,173451,12,12) outside any screen - subsequent actions might not work as expected

[error] Region(111925,179265,12,12) outside any screen - subsequent actions might not work as expected

I dont know what is this Region which is moving out of the screen and I do not understand why the observer is not getting stopped when pcheck function is triggered for the first time ?!
