[microsoft/vscode] After Update: VS Code Opens Multiple Windows on Startup and Claude Latency Makes Models Unusable

### ROOT CAUSE 1. **Multiple Windows on Startup**: This issue likely stems from a bug in the VS Code update affecting window management. The update might have altered how VS Code handles multiple instances or reuses windows, leading to unintended behavior. This could be due to corrupted configuration files, a faulty update, or a conflict with extensions. 2. **Claude Model Latency**: The slow performance of Claude models is likely due to inefficient resource allocation or suboptimal configuration of the AI extension. The models might not be leveraging GPU acceleration properly, or there could be a bottleneck in the system (e.g., outdated drivers, insufficient RAM, or conflicts with other extensions). ### CODE FIX 1. **Fix Multiple Windows Issue**: - **Delete Configuration Files**: Navigate to your VS Code settings directory and delete the `windowState` file. This file stores window layouts and can cause corrupted state after updates. On Windows, the path is: ``` %APPDATA%\Code\User\workspaceStorage\windowState ``` After deletion, restart VS Code to generate a fresh configuration. - **Check for Duplicate Launches**: Ensure no startup scripts or shortcuts are triggering multiple instances. Check the Task Scheduler or any custom scripts that might launch VS Code. - **Update VS Code**: Install the latest version from [VS Code's official site](https://code.visualstudio.com/), as the issue might be resolved in a patch release. 2. **Fix Claude Model Latency**: - **Update Extensions**: Ensure the Claude extension and all related AI tools are updated to their latest versions. Outdated extensions can cause performance issues. - **Enable GPU Acceleration**: If the Claude extension supports GPU offloading, configure it to use your NVIDIA GPU. Check the extension’s documentation for settings like `useGpu` or similar. - **Optimize System Resources**: - Update GPU drivers from the [NVIDIA website](https://www.nvidia.com/Download/index.aspx). - Close unnecessary applications to free up RAM and CPU resources. - Adjust VS Code settings to limit background processes (e.g., `workbench.editor.enableAsyncPreview`) if needed. If the issue persists, gather logs from VS Code (`%APPDATA%\Code\logs`) and report them to the VS Code team or the Claude extension’s support channel.
