I haven’t been able to reproduce on a blank install yet. But it happens on a production site, the staging, and a completely different site with all other plugins deactivated.
I can confirm that 1.3.3.1 with 6.3 works fine, but once I update to 6.4 it gets sluggish.
Happens with just one page open, and occurs instantly.
Happy to provide access to the staging site if it’d be helpful
Ah yes, the typing experience looks to be much better. Thank you!
The only thing is that I have noticed that the Cwicly block inspector is still sluggish in Firefox as well. After a quick test, it might only be related to global classes.
Ex. try changing the padding for a div on the block class, and then try adjusting it when a global class is selected.
