Now time in transport module lags behind

I just installed the X3d Producer trial today, and the first thing I notice is that during playback, the time displayed in the transport module is actually lagging behind the audio, by maybe 150-200ms, at a guess? I wouldn't have been too surprised (though mildly disappointed) if the time was ahead of the audio, because of the usual latency stuff. But in this case, I am hearing the audio for beat 1 before the time displays beat 1. I think it wasn't the case in 8.5, or at least it was less obvious there.
 
Is this a known issue? The only explanation I can think of is that perhaps something is misreporting latency, so the audio engine thinks it is further behind than it really is?

Just tried the Pause key - it definitely wasn't that. In fact, what I think I'm seeing is that at least one plugin (Superior Drummer 2) is playing back early. I took a screenshot and it's clear that the timeline and the time display are in perfect sync. Yet, with MIDI events right on the grid, I am hearing them before the start of each beat. Odd.

I presume this is with x64 Superior so it's not the Bitbridge bug...?
 
If you disable Stop At Project End in the track view options, and just play a new blank project with the playback metronome enabled, do you see/hear a discrepancy between the Now time and the clicks? And if you then add a Superior Drummer track, which two of the three remain in sync? Or does the problem not manifest in a new project?
