Root Cause

The Claude Desktop app appears blurry on my high-DPI ultrawide display. The standard fix (right-click .exe > Properties > Compatibility > Override DPI scaling) is not possible because the MSIX packaging installs to the protected WindowsApps folder, blocking access to compatibility settings.

Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

The Claude Desktop app appears blurry on my high-DPI ultrawide display. The standard fix (right-click .exe > Properties > Compatibility > Override DPI scaling) is not possible because the MSIX packaging installs to the protected WindowsApps folder, blocking access to compatibility settings.

System:

  • Windows 11
  • Display: Ultrawide 5120x1440, custom scaling 225%
  • Claude Desktop version: Claude_1.9255.2.0_x64 (MSIX/WindowsApps)

What I tried:

  • Set Windows display scaling to 100% — no improvement
  • Reinstalled from claude.ai/download — still installs as MSIX
  • Ran as administrator — still blurry

What Should Happen?

App should render crisply on high-DPI displays. Please provide a standalone .exe installer that allows DPI compatibility settings to be configured, similar to how Discord and VS Code handle this.

Steps to Reproduce

  1. Download Claude Desktop from claude.ai/download on Windows 11
  2. Install and launch the app
  3. On a high-DPI ultrawide display (5120x1440, 225% scaling), app appears blurry
  4. Attempt to fix by right-clicking the .exe for DPI compatibility settings — not possible as app installs to protected WindowsApps folder
