Futureboard Patch Record

This repository contains local changes to vendored libraries. These changes are intentional and should be preserved when updating dependencies.

GPUI

Path: crates/gpui

Reason: Futureboard Studio needs app-specific native DAW desktop behavior and rendering fixes that are not present in upstream GPUI.

Current patches:

Uses the standard GPUI/platform cursor styles for the native Studio; the former Futureboard cursor extension and bundled cursor assets were removed.
Added derivative-based SDF coverage and zero-alpha guards to the Windows HLSL and WGPU WGSL render paths.
Enabled WGPU's DirectX 12 backend in the Futureboard workspace for Windows GPU-rendered surfaces.
Guarded macOS traffic-light repositioning against missing standard window buttons, which AppKit removes for sheets and for non-minimizable style masks.
Windows: translate_accelerator asks only GPUI's own windows whether they handled a key. It asks by sending a private message and reading the reply, treating 0 as "handled" — and DefWindowProc answers 0 to any message it does not know, so upstream every other window in the process claimed every key aimed at it and the loop dropped the message before dispatching it. A DAW has such windows on the same queue (plug-in editor views, hosted browsers, editor shell chrome), and their keystrokes never reached their window procedures.
Windows: WM_MOUSEACTIVATE activates a window only when it is not already active, and activate() does nothing past restoring a minimized window when the window is already in the foreground. Both used to re-run activation and SetFocus on the window itself, which pulled focus off a plug-in editor's own popup (a JUCE dropdown) and closed it as it opened.
