+description:
+Bug 1645671 [Linux/VA-API] Create DMABufSurfaceWrapper directly at nsTAttay and disable DMABufSurfaceWrapper class copy and assignment constructors, r?jya
+
+When DMABufSurfaceWrapper is added to nsTArray, a temporary local DMABufSurfaceWrapper object is created. When the temporary
+object is deleted after the adding, associated dmabuf data is released which leads to rendering artifact during VA-API video playback.
+
+As a fix in this patch we create DMABufSurfaceWrapper 'in-place' at nsTAttay.
+We also disable DMABufSurfaceWrapper class copy and assignment constructors to avoid similar potential issues.
