Live preview issues in recent releases

[sghelichkhani]

In recent releases I have noticed that something in the way live preview works has changed that is not desirable. It is mainly that when (at least in firefox) something in the qd file is modified, and the browser tries to refresh, the browser often jumps back and forth, mostly to the beginning of the file.

So I was wondering if there is anything to be done to go back to the smoother old behaviour.

I am on MacOS, and have tried Brew + manual installation of qd. Any ideas?

Hi @sghelichkhani, are you on 1.9.x? The live preview has been redesigned in order to feel smoother. If so, can you provide a demonstration of the issue please?

Yes on 1.9.1

Don't know how to best explain it, so maybe this short screen recording does the job best. It's about the fact that the browser refreshes by going to the start, which is not ideal to make changes and see the result.

Got it, it's related to slides only. You may temporarily downgrade to 1.8.0 and I'm going to work on a hotfix.

@sghelichkhani v1.9.2 is out now and the issue has been fixed.

The problem was related to the preview's double buffers that would not sync their URL to the same slide number.

PS: you might want to try out the new extension for VS Code / Cursor :)
