[BUG] Text truncation/clipping on left side of Claude Code output panel

Environment

• Platform: Anthropic API (Claude Pro subscription)
• Claude Code version: 2.0.73
• Operating System: Windows 10/11 (issue occurs on desktop, NOT on laptop)
• Terminal: VS Code integrated Claude Code panel + standalone PowerShell

Bug Description

Text displayed in the Claude Code output panel is being truncated/clipped on the left side. Content that should be centered or indented has its left portion cut off, making it unreadable.

For example, text that should read:

(Skill guides + MCP validates)
+ Claude plugins)

Displays as:

e + MCP validates)
+ Claude plugins)

The beginning of lines is being cut off.

Steps to Reproduce

1. Open Claude Code in VS Code (dedicated Claude Code view, not terminal)
2. Have Claude Code read a markdown file containing centered text, ASCII diagrams, or indented content
3. Observe that the left side of wide/centered content is truncated

Expected Behavior

All text should be fully visible, matching what appears in the actual file when opened in an editor.

Actual Behavior

Left portion of centered/indented text is clipped off. Only the right portion of lines is visible.

Troubleshooting Already Attempted

• ✅ Verified the underlying .md file is correct (opens fine in VS Code editor)
• ✅ Terminal buffer size is normal (120x30 width/height)
• ✅ Basic PowerShell Write-Host with leading spaces renders correctly
• ✅ Widened Claude Code panel to maximum width - no change
• ✅ Issue does NOT occur on laptop with same Claude Code version
• ❌ Issue persists on desktop only

Additional Context

• Desktop: [YOUR DISPLAY SCALING 100%, RESOLUTION 2560 x 1440, GPU 8GB NVIDIA GeForce RTX 3060Ti]

This appears to be a rendering issue specific to Claude Code's output display, possibly related to display scaling or GPU rendering, since:

1. The actual files are not corrupted
2. Standard terminal output with leading spaces works fine
3. The issue is machine-specific (desktop only, laptop works)
