VU in GOP on Mac

Hi, There is a problem with the graphic rendering of the VU when used within a GOP.
What I expect: Capture_d_écran_2017-02-05_à_11.40.24 What I get: Capture_d_écran_2017-02-05_à_11.40.22 My PurrData version is 54.0.2840.71 (2840.71)
My MacOS is Sierra 12.10.3

The patch: strange-vu.pd
