[BUG] Claude Desktop blurry on high-DPI ultrawide display due to MSIX packaging blocking DPI override

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.
