I also get the mouse shaking randomly when it's idle. Happens in bios too.
Haven't had a look at the firmware version but I bought it new about a week ago.
1-pixel mouse pointer jittering / crawling randomly brownian-motion style?
Solution:
Check your mousepad too, AND check desk vibrations (e.g. actively-cooled tower PC on desk).
Sometimes it's so dark to infrared wavelengths that it's just picture noise to the mouse sensor (which is just a simple ultra high speed camera of a few pixels, often 20x230 or 32x32 or so pixels running at thousands of frames per second). Changing mouse pads often fixes the shaking-randomly effect.
Also, higher poll higher DPI can be more prone to jitter from weak reflections from mousepads (just a noisy picture to mouse sensor).
Different sensors have different sensitivities so you may need to try a couple brands of mousepads, to get jitter-free high-DPI high-poll operation.
Also if you eat a lot of chips and smear all over a glossy mousepad as you drag your mouse-holding wrist around, you might be changing your mousepad's reflectivity to the mouse sensor (again, it's a camera, and subject to image noise), and creating unexpected reflectivity effects for your mouse sensor.
Sometimes the visible-light texture of a mousepad is different in near-infrared wavelengths.
This is not a Razer-specific operation, but a problem of multithousand frame per second ultra high speed near-infrared camera that's part of the sensor in the Razer 8KHz -- you need a good mousepad that has relatively high contrast to a near-infrared camera, no choice -- so that the mouse firmware is getting grain-free noise-free mousepad images from the mouse sensor (aka 8000fps-20,000fps high speed low-rez camera)
Play the mousepad roulette to fix this! And makes sure your desk surface is vibration-free. Keep your mousepad feet clean, and don't put fan-running devices on the same surface as the mouse -- even vibrations from a fan can create jitter on ultra-high-sensitivity mice.
If you must put your desktop computer ON the same desk as your mousepad, then you must absolutely put some really damn good vibration-isolating softness under your computer feet! (of at least 2 kind -- hard rubber AND soft rubber/neoprene -- for the multiple harmonics that a computer emits into a desk surface)
You don't have to sabotage yourself down to only 400dpi or 800dpi in high-DPI-friendly games like Fornite just because you want to keep a crappy/worn/dirty mousepad or don't care about desk vibration hygeine.
Playing 3200dpi+ while concurrently running at 8000Hz requires a bit of mousepad care (selection/cleanliness/etc) and keeping vibrations away from your mousepad area.
You can also add some software-based jitter filtering (some mice sensors have that built in), but not everyone likes software based filtering or mouse-firmware-based jitter filtering and would rather optimize their desk instead. The rawest mouse input of the ultra high speed kind can have more jitter after all, so pick your poison -- want lag-increasing jitter cancellation in software -- or want to fix your mousepad IR-texture-visibility and desk vibrations instead?
