I have a Mirage with a manual transmission so I have no experience with the CVT. I understand it is programmed to try to keep engine RPMs low for fuel economy. Your case sounds like it's trying too hard?
I wonder if one of your vehicle's sensors is reporting false information. Are you are able to monitor any of the on-board diagnostics, whether on your own or through a mechanic's garage?
The Jatco CVT used in this generation Mirage has a dual-range gear. Your description sounds like it is shifting into high range, which would be expected.
