Just bumping this in case it got missed.
I’ve had to roll back to Zettlr 3.6, because version 4 has become almost unusable on my machine. I’m seeing frequent stalls and long periods of non‑responsiveness.
Since reverting to 3.6 everything is smooth again, no lag at all, so it really does seem like something specific to version 4.
Is anyone else experiencing this, or is there any known issue being tracked?
