Hi there, 

We are sorry about the experience with Lightroom. Do you see these lines in the exported images?

Would you mind going to the Preference for Lightroom, then Performance and disable the option to Use Graphics Processor? Once done, please quit and relaunch Lightroom to check if that helps.

If you do not observe the lines after disabling the Graphics Card, please uninstall the drivers for the NVIDIA card and install the latest drivers from the manufacturers website before enabling the option to Use Graphics Processor again.

Regards,
