What's Wrong?

Description

Significant performance degradation after updating from 1.1.5749 to 1.1.7714 on Linux.
The app feels noticeably slower and uses ~2x more memory than before.

Environment

• OS: Ubuntu 22.04 (Linux 5.15.0-171-generic)
• CPU: Intel Core i5-8365U (8 cores)
• RAM: 16 GB
• Claude Desktop: 1.1.7714 (regression from 1.1.5749)
• Electron: 41.0.3
• Display: Wayland native (CLAUDE_USE_WAYLAND=1)

Observed behavior

• Electron processes consume ~2.1 GB RAM on startup (fresh launch)
• Previous version (1.1.5749) was fluid with the same MCP server configuration
• UI freezes and goes white under normal usage
• Slowness persists even after disabling non-essential MCP servers

Expected behavior

Same memory usage and fluidity as 1.1.5749 (~400-600 MB after fresh launch)

MCP servers active

~6 servers: Notion, Slack, Figma, SeqoneLens, Supabase, scheduled-tasks

Workarounds attempted

• Disabled PostHog, HubSpot, Gmail MCP servers → partial improvement
• Switched to native Wayland mode → partial improvement
• Restarting Claude Desktop periodically → temporary relief

What Should Happen?

Same memory usage and fluidity as 1.1.5749 (~400-600 MB after fresh launch, no UI freezes)
