Contour needs visible renderer or noop/memfail

hi guys

  1. _I solved it by positioning the other renderer ‘behind’ the fullscreen one on monitor B, hence the videostream was on the same device._this trick works for me only on main screen …
  2. cant get “shared memory” working for me
  3. “flash”?..never tried yet
    @ karistouf
    sorry I still dont get your “ventilating” trick…
    btw i managed secure and complex FX chain with beta23 by putting all (hidden and preview) renderers on the same 2nd screen, but beta25…olala
