Hi again ...

I can confirm this, infact rewriting in this way doesnt trigger taint

if button == "LeftButton" then
      ToggleGuildFrame()
end

So I think I can fix in this way removing the:

CommunitiesFrame:SetDisplayMode(COMMUNITIES_FRAME_DISPLAY_MODES.ROSTER)

Thanks again for the fantastic input.
