I did not see the problem with pref dom.webgpu.swap-chain.external-texture-dx12 = true on Windows. From it, remote texture seemed unregistered during readback.

The problem happens when using a raw buffer, and the swap chain is destroyed before the Readback callback is completed. In this case the present is aborted causing the flash. The webgpu canvas code needs to delay destruction till all readbacks are completed.
