Plan mode slow and glitching the screen

Steps to Reproduce

Request a plan

Expected Behavior

Fluid and “fast” plan building, without screen refreshes and flicks

I was just about to come in here and post this - but glad someone else is seeing it. It started happening since the update yesterday to 2.3.29. A plan that used to take 30 seconds, now takes 10 mins at least and the IDE is totally unusable. I am running Windows, but SSH’ed into a LInux server.

I got the exact same issue. I am running macOS, SSH connecting to a Linux server.

Will have a fix in early access on 2.3.31 by later tonight.

Is there any estimate of when it will be available for download?

Have updated now. Issue still exists though.

I am currently working around it by just closing the Plan when it comes up in the Editor.
