[BUG]: Integrated terminal is completely unresponsive (blank screen, no input) #21469

Description

The integrated terminal in OpenCode is completely unresponsive - it displays a blank white screen and cannot receive any keyboard input. The terminal tab shows (e.g., 'Terminal 1'), but the content area remains empty and typing does nothing.

Current behavior:

• Terminal opens but shows blank white screen
• No shell prompt displayed (no PowerShell/cmd output)
• Keyboard input is not received (cannot type commands)
• Terminal is completely unusable

Expected behavior:

• Terminal should display shell prompt (PowerShell or CMD)
• Should accept keyboard input and execute commands
• Should show command output normally

Plugins

N/A (core functionality issue)

OpenCode version

Latest version (as of April 2026)

Steps to reproduce

1. Open OpenCode application
2. Click the terminal panel toggle (or press shortcut) to open integrated terminal
3. Click '+' to create new terminal
4. Attempt to type any command

Result: Terminal shows blank screen, no input accepted

Operating System

Windows 11

Terminal

OpenCode integrated terminal (built-in)

Additional context:

• Restarting OpenCode does not resolve the issue
• Closing and reopening terminal tabs does not help
• PowerShell 5.1 and CMD both fail to load in the terminal
• This appears to be a terminal rendering layer bug in the OpenCode client
