Title:
  IDE crash

Status in Sikuli:
  New

Bug description:
  Hi!

  I am using Sikulix 2.0.4 on Windows 10 64bit, JAVA 11, 2 large sized
  Monitors (3440x1440 + 2560x1440 as one display, NVIDIA).

  Sikulix crashes (meaning: it does not process anymore, does not write
  logfiles, ALT-SHIFT-C does not work, JAVA needs to be killed in
  taskmanager to restart sikulix) within following function in about 1
  of 10 cases. only when it tries to OCR read text in an area where
  there is no text:

  def text_shrink(Reg):  # continously decrease region until OCR gets a match
          texts=False
          Reg=Reg.grow(30,30,0,0) 
          while (texts==False or len(texts)<=2) and Reg.getW()>20:
              Reg=Reg.grow(-30,-30,0,0) 
              texts=ExtractAlphanumeric_all(Reg.text()).strip()    #crash here on OCR      
          return texts

  The images for this particular run where the crash happend is
  attached.

  Here the debug log (4):
