Wine's OpenGL/EGL backend has a bug where `wglSwapBuffers` always targets the same EGL surface regardless of HWND, which breaks DockWidget rendering (Explorer, Properties, Toolbox all stay black). + +WineD3D translates D3D11 calls to OpenGL internally but manages per-window swapchains correctly. The FFlags force this path: + +```json +{ + "FFlagDebugGraphicsPreferD3D11": true, + "FFlagDebugGraphicsDisableVulkan": true, + "FFlagDebugGraphicsDisableD3D11FL10": true, + "FFlagDebugGraphicsDisableOpenGL": true +} +``` + +### Shader Patching + +Studio's GLSL shader pack declares `#version 150` but uses `unpackHalf2x16()`, which requires GLSL 4.20+. NVIDIA/AMD drivers are lenient about this; Mesa's llvmpipe is strict and rejects the shaders. + +The fix is a binary patch: replace all `#version 150` with `#version 420` in `shaders/shaders_glsl3.pack`. Both strings are exactly 12 bytes, so the patch is safe and in-place. + +### Authentication + +Studio expects three entries in Windows Credential Manager: + +1. `https://www.roblox.com:RobloxStudioAuthuserid` → numeric user ID +2. `https://www.roblox.com:RobloxStudioAuthCookies` → `.ROBLOSECURITY` (cookie name) +3. `https://www.roblox.com:RobloxStudioAuth.ROBLOSECURITY{userId}` → the cookie value + +The `linux inject-credentials` command: +1.
