VST-Internal Sequencer not Playing in Sync with Cubase


I have one strange problem with the internal sequencer of the VST Atlas 2.
From bar 1-4 the sequencer play’s out of sync to the DAW - the sequencer starts playing a few milliseconds before the Metronome starts. From bar 5 it’s correcting itself and playing in sync.

See the video for an example.

I am using Cubase 11 on Win10. Changing buffersize, ASIO-Guard etc. doesn´t make a difference.

I would get in touch with the maker of the plugin.

Yeah thats probably the best.
What I find strange is, that another user reported, that it works without any problems in C10.5, so I thought this might be a known issue in C11
