# Objective

Fix overflow of terminal background in the Agent Thread. Related to
#64163.

## Solution

- Added `terminal_view::TerminalView::background_corner_radii` which can
be optionally set in order to render the terminal view with rounded
corners
- Updated `agent_ui::entry_view_state::create_terminal` in order to
always set the `TerminalViews` background corner radii, for the bottom
corners. Since GPUI doesn't expose the radius values used by
`rounded_md`/`rounded_b_md`, these values have been hardcoded and
documented here.
- Updated `terminal_view::terminal_element::TerminalElement::paint` in
order to use the same corner radii for the quad being painted, as the
corner radii used in the `TerminalView` it is being painted within

## Testing

Manually verified by using a light theme, overriding the
`terminal.background` color to something like `#000000` and then asking
the agent to run a terminal command.
