            Bug ID: 237424
           Summary: [GPUProcess] Drawing video on canvas results in black
                    canvas if GPU Process: Canvas rendering is on
           Product: WebKit
           Version: Safari 15
          Hardware: Mac (Apple Silicon)
                OS: macOS 12
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas
          Assignee: webkit-unassigned at lists.webkit.org

When video uses Hls stream as a source in Safari, and when I want to draw that video onto the canvas using drawImage(video, 0, 0, w, h) (https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/drawImage), canvas results in a black image.
If I turn off the experimental feature- GPU Process: Canvas Rendering, everything works as expected. And it worked as expected in previous Safari versions.
