Welcome to the Lenovo Forums.
From your description, it seems like there's a problem with the GPU.
If you get errors, you may need to contact lenovo for service.

For units with switchable graphics (Intel + AMD), it's normal for dxdiag to show the Intel HD Graphics as it's the primary GPU that the system uses before it switches to the AMD Graphics.
The several errors that you saw on the Intel HD Graphics might explain the flickering issue that you have as this indicates video memory errors. I recommend that you report these findings by contacting lenovo as you may need to send the unit for service.
