David GhegheaandClaude Opus 5.5 629cfec630 fix(nvidia): keep threaded optimizations off for driver 580 
With __GL_THREADED_OPTIMIZATIONS=1, NVIDIA 580 (the last branch for Pascal
GPUs) with egl-x11 1.0.6 rejects the X11 EGLDisplay with EGL_BAD_DISPLAY on
every thread that has a context current. A native EGL program reproduces it
outside Darling. In the Riot client the main thread loses EGL after its first
window frame, so CGLCreateContext fails with error 10004 and the game window
stays black. Default the launcher to 0; setting the variable restores 1.

CGLDestroyWindow also returns early for the NULL window CGLGetWindow gives
when eglCreateWindowSurface fails, instead of passing EGL_NO_SURFACE on.

+ * the M58b IOSurface work, and fileports via the M58 kobject machinery).
+ *
+ * So the shim keeps NO guest-side state. The display link's state lives in
+ * a per-pid host file; Create/Start/SetOutputCallback/Stop are trivial side
+ * effects on that file; the runloop timer fires every 1/60 s and reads the
+ * file fresh each tick, invoking Chromium's callback with a plausible
+ * CVTimeStamp. The timer itself fires (verified: continuous ~60 Hz records).

+ * backed by Mesa/EGL, where CGLTexImageIOSurface2D can only COPY the IOSurface

+ * every published frame was metadata-correct but all-zero.
+ *
+ * The fix: at every cross-process handoff point (IOSurfaceCreateMachPort is
+ * called by the sender — GPU process for the display surface, renderer process
+ * for its GMB content surfaces), copy the bound GL texture back into the
+ * IOSurface memory via OpenGL.framework's CGLReadbackIOSurface. The binding
+ * table it consults is per-process, so this is a harmless no-op in processes
+ * that never GL-bound the surface (browser, software path).
+ *
+ * OpenGL.framework is resolved with a private dlopen: IOSurface cannot link
+ * OpenGL (OpenGL links IOSurface — a cycle), and per the M57bo lesson adding
+ * CGL symbols to IOSurface's dependency symbol scope would leak them to every
+ * dependent. In GL processes the framework is already loaded (ANGLE depends on
