Up to date laptop/WSLg still shows [WARN: COPY MODE]

[jessey-git]

All sources seem to indicate that as long as we're using Mesa 21+, with a recent kernel, and recent nVidia drivers then COPY MODE should not be an issue, but it still seems to be.

[EDIT]: Just found the workaround to at least get nVidia to be used rather than the integrated Intel GPU:
export MESA_D3D12_DEFAULT_ADAPTER_NAME="nvidia"

However that still doesn't stop [WARN: COPY MODE] from being present :(

Hmm, well a full system reboot seems to have cleared that up that warning message.

If anyone has the same problem immediately after creating the WSL install, give your system another reboot and see if that helps.
