Thank you for reporting a bug to Unity. We have reviewed the issue carefully, and in this case, the team is unable to prioritize fixing this bug. There are a number of reasons we make this decision, including the impact and severity of the issue across our user and customer base, and the possibility that future plans may solve the problem in a different way, or that a workaround for the bug may be available. Today we will be closing this case. Thank you again for taking the time to report this issue, and please let us know if there is anything else that changes the impact or severity of this issue.

Steps to reproduce:

Create a new Unity project using the Universal 3D template
Create a UI Document asset (Assets > Create > UI Toolkit > UI Document)
Double click the new UI Document asset to open it in the UI Builder window
Maximise the UI Builder window
Click and drag any component to the Viewport
Observe the UI Builder window

Actual results: Clicking and dragging the component is extremely slow/choppy and lagging

Expected results: Clicking and dragging the component is smooth and quick

Reproducible with versions: 6000.3.0a1, 6000.3.0a4

Not reproducible with versions: 6000.0.54f1, 6000.1.14f1, 6000.2.0b13

Tested on (OS): Ubuntu 24.04

Notes:

Does not reproduce on macOS Silicon Sequoia 15.5
Does not reproduce if the UI Builder is not maximised
Also reproduces with other windows, like the Build Profiles window
