PDC problem with Lex Native in Cubase 8.0? Reverb & Delay Plugins

PDC problem with Lex Native in Cubase 8.0?

Edited to add: This was in Windows 8.1

1. I start a Cubase 8.0 project and add an Instrument Track (I'm testing with Pianoteq).

2. I add an FX Track and activate a send from the Instrument Track to the FX Track.

3. I phase invert the FX Track to test that everything is synchronized, and it nulls with the Instrument Track, so everything is synchronized so far.

4. I add Lex Hall (VST2) as an insert on the FX Track, and then I Bypass Lex Hall.

5. Now things are not synchronized. The two tracks aren't nulling anymore. Shouldn't they be nulling? (When I repeat the experiment using Phoenix Verb (VST2) in place of Lex Hall, synchronization is all fine. When I repeat the experiment using Lex Hall and Reaper instead of Cubase 8.0, synchronization is fine.)

6. Next I deactivate Lex Hall, and synchronization works fine again.

Why should a bypassed plugin throw off the synchronization?

Edited to add: It makes no difference whether I have ASIO Guard activated (set to Normal Level). I've tested with ASIO Guard on and also with it off.

Try toggling Constrain Delay Compensation in Cubase, trying it both ways.

Turning on Constrain temporarily fixes the synchronization, but Constrain needs to be off while doing Export Audio Mixdown (and while mixing).

This seems like a bug. Export Audio Mixdown renders different audio depending on whether Lex Hall is bypassed or deactivated.

Interesting, I'm going to test this in Cubase 5 as I notice by the time I get to the final mix of a project the timing often doesn't feel as solid as the unmixed version. Maybe this is the reason.

That was Lex PCM v1.3.7. Apparently it's been fixed in v1.3.8:
