Problem description

Thank you for your work.

It can be used normally on MacOS Tahoe 26.0 (25A353)
But on version 2.15.0, there will be a loss of focus, and severe memory leaks like over 1g
the beta feature is not enabled

Is the issue consistently reproducible?

Reproducible

Steps to Reproduce

open input translate window, paste something, it probably loss focus, and make it slow
Or open settings window, when the window is cancelled by other operations, it is not released normally, which will cause more memory to be consumed

Expected result

Fix memory leaks and missing focus

Proposed solution (optional)

If use swift window management, be sure to ensure that its life cycle is normal. Swift windows are always easy to leak memory

Device type and OS version

MacOS 26 Tahoe
