Communication stucks toggling OSD2_ENABLED on and off

ArduCopter Copter 3.6
1

I think I’ve found a bug either in MP or ArduCopter related to a autofolded parameters like OSD1… and OSD2…
To reproduce that simply repeat these steps:

  1. Connect with MP, open Parameters Tree
  2. Change OSD2_ENABLED = 1, click Refresh
  3. Change OSD2_ENABLED = 0, click Refresh
  4. Repeat steps 2 and 3 and MP will stuck on refreshing parameters.
    Most of the times it stucks quickly right after the first repeat.

For me it does reproduce on PixRacer, so I have a customized FW that supports OSD.

Can anybody having a FC with an integrated OSD check the steps above on a official 3.6 firmware? To confirm that issue.
