What's the problem? Describe what went wrong.

Gradually increasing FPS fluctuations over time with System Interrupts spiking to well in excess of 10 to 20% after a few hours. Occurs only with Xinput enabled and Wiimote set to real.

What steps will reproduce the problem?

Start a Gamecube game with XInput configured and Real Wii Remote set for emulated Bluetooth. Then play for a few hours without allowing the controller to be disconnected. Can also catch a glimpse of the issue after half an hour by pausing the emu and opening task manager and observe System Interrupts while rapidly moving both sticks.
