Summary
I’m experiencing a strange issue with the Unreal Engine Editor — the game itself runs smoothly, but the editor UI (such as menus, content browser, and explorer) is lagging behind the mouse movements. There’s a noticeable delay when hovering over buttons or moving the cursor around the editor interface.
This issue persists in version 5.4 and is still happening in 5.6.
Has anyone else encountered this? Is there a known fix or workaround?
System specs and additional context:
Processor 12th Gen Intel(R) Core™ i7-12700H 2.70 GHz
Installed RAM 16.0 GB (15.7 GB usable)
Happens even on a fresh project
