Experiencing this too - stuttering in the editor making it completely unusable at times. Narrowed it down to the studio telemetry plugin with a slow running blocking timer every 0.5.

Unfortunately I can’t disable this plugin as it’s depended on by the “asset search” plugin which is in turn depended on by the “flow” plugin which my project is using. For those who are unable to disable the studio telemetry plugin, you can stop it from stuttering by adding the following lines to your project’s DefaultEngine.ini:
Windows:
; Studio Telemetry Settings
[StudioTelemetry.Log]
FileName="nul"
Linux:
; Studio Telemetry Settings
[StudioTelemetry.Log]
FolderPath="/dev/null"
This effectively cancels out the expensive synchronous file writes that it’s doing.
