[Bug]: Terminal occasionally displays raw ANSI escape sequences when opened

[Sy-D]

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/desktop

Steps to reproduce

1. Open the project.
2. Open the integrated terminal.
3. Repeat closing and reopening the terminal several times.
4. Occasionally, the terminal starts with garbled output containing visible ANSI escape sequences.

Expected behavior

The terminal should interpret ANSI escape sequences correctly and display the prompt and startup output with normal formatting.

Actual behavior

The terminal sometimes prints ANSI escape/control sequences as plain text, for example sequences beginning with characters such as:

^[4;...
^[38;...
^[15;...

This causes the startup output and prompt to appear corrupted. Exiting the active shell via ctrl+x or ctrl+c doenst work. After terminating and reopening the terminal, it usually works normally again. This happened after running bun run dev on a nextjs project.
