           Summary: WebGL2 clearBuffer results are lost if drawing buffer
                    is pending a clear in certain cases
           Product: WebKit
           Version: WebKit Local Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGL
          Assignee: webkit-unassigned at lists.webkit.org

WebGL2 clearBuffer results are lost if drawing buffer is pending a clear in certain cases

1) Drawing buffer is prepared for display
2) clearBuffer is called
3) ..before drawing buffer is cleared
4) ..while having clip
5) will just run the clearBuffer

Instead, the pending clear should be flushed and then the clearBuffer should be done.
