Details

Most WR captures we receive from the users are done with DC enabled these days. We can't replay the "frame" level of these captures without Wrench establishing a native compositor itself, or at least pretending that it does the native compositing.

Severity: -- → N/A

Here are some of the external bits the current DirectComposition compositors uses:

  • prefs (gfx_webrender_debug_dcomp_counter, gfx_webrender_debug_dcomp_redraw_regions)
  • gfxVars::UseWebRenderDCompVideoOverlayWin,
  • RenderThread interaction:
    • Error notification
    • GetRenderTexture
