It's worth mentioning that even with the downgraded bios the mouse cursor frequently gets stuck requiring a screen flex to fix.
In addition the downgraded bios exposes similar sticking on Windows. So I can only imagine that resolving this was the purpose of the bios update in the first place.
Once updated to the latest bios cursor behaviour is good on Windows.
