I have TVer 5 and I have tried that, and it still disables it. It doesn't do it for performance reasons, it does it because TVer is incompatible with the theme. I don't know the exact reason why but that's how it is.
Check your settings and you shall see that it do inactivates it, but only because to increase peformance, not what you belive, you can teamviewer keep the aero enabled if you set that in the settings.
