            Bug ID: 278451
           Summary: REGRESSION(282416 at main): [GTK][WPE] GPU process
                    crashes in PlatformDisplay::shared()

           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: Gtk, Regression
          Severity: Normal
          Priority: P2

Since 282416 at main that PlatformDisplay needs to be explicitly initialized and the GPU process isn't supposed to use PlatformDisplay (yet) so it doesn't initialize it (yest). But GraphicsContextGLGBM creates a fence in prepareForDisplay() and GLFence uses PlatformDisplay. For now we can remove the fence since it's unused.
