Window not resizing correctly

Description

I noticed that after an update a few months ago the main window stopped scaling correctly. When maximized it is cut off and manually resizing is not working for me:

Steps to Reproduce

1. Open proxyman
2. Double tap or resize from the resizing menu (top left)
3. See how window is cut off on the right or left side.

Current Behavior

When double tapping top toolbar the app expands to full screen but does not respect the actually screen size expanding beyond the desk size.

Also trying to resize the window manually is not working either, shows indicator to resize window but does not do anything.

Note:

Full screen mode "Entire Screen" does work:

Expected Behavior

When I double tap the top bar to expand the window to full screen the app doesn't go extend the screen size and allows viewing the whole app content.

I should also be able to resize by dragging corners or sides of window.

Environment

• App version: Proxyman Version 5.19.0 (51900) | macOS: Version 15.3.1 (Build 24D70)
• macOS version: macOS Sequoia 15.3.1 (24D70) Apple M3 Macbook pro

No source files, tests, or code entry points are identified. Start by reproducing the issue on macOS 15.3.1 with Proxyman 5.19.0 using the listed maximize and manual-resize steps, and compare them with Entire Screen mode. Done means maximized windows fit the desktop and dragging their edges or corners resizes them normally.
