Glitches at bars start sequencing

Hi
With a quite heavy template (nearly full orchestra with light EWQLSO presets), I suffer quite systematic glitches during playback in edit mode, at the precise moment when the playback marker jumps from one bar to the other.
I already tried to set my ASIO drivers buffer since I'm around 80% of my CPU capacity, but it doesn't change anything.
Do you guys encounter the same behavior?
Is it a Notion issue?
