Border toggle causes editor window resize and toolbar to become hidden

[yyovil]

Description

When enabling the Border toggle in the video editor, the entire editor window resizes incorrectly, causing the layout to shift upwards. This results in the top toolbar (containing Export button, Presets dropdown, and other controls) becoming hidden/clipped above the visible area, while a white bar appears at the bottom of the window.

Reproduction

1. Open a video recording in the Cap editor
2. Navigate to the Border settings in the right panel
3. Toggle the Border switch from OFF to ON
4. Observe the window resize and layout shift

Expected Behavior

The Border toggle should only affect the border appearance on the video recording itself, without causing any layout shift or window resizing issues in the editor interface. All UI elements should remain visible and properly positioned.

Actual Behavior

When the Border toggle is enabled:

• The entire editor layout shifts upwards
• The top toolbar (Export, Presets, etc.) becomes hidden above the visible window area
• A white bar appears at the bottom of the window
• The editor becomes difficult to use as critical controls are no longer accessible

Screenshots

Before (Border OFF):
The editor displays correctly with all UI elements visible, including the top toolbar.

After (Border ON):
The layout shifts upward, hiding the toolbar and showing white space at the bottom.

Additional Context

• Cap version: 0.3.83 (based on recent issues)
• Operating system, version: macOS
• This appears to be a layout/rendering issue specific to when border settings are modified

Impact

This bug makes the editor unusable when borders are enabled, as users cannot access the Export button or other essential controls in the toolbar.
