Hi everyone,
If you've experienced this issue and you're able to upgrade to 3.6.5,
I'd love to get your feedback on the responsiveness of the webadmin UI

Best wishes,
Greg

We have patches in review that should fix this in 3.6.5. The
underlying problem is a couple of JavaScript memory leaks.
Best wishes,
