When I was in Cuba my mouse under Windows 10 would act funny at times, moving without input or refusing to move.
After a while I figured out that the touch screen was causing the problems when the air got too humid.
Since touch screens did not work under my version of Haiku I never noticed any problem with it. But just before coming to Florida I did a major upgrade using the nightlies.
It took an entire day fighting with machine before I remembered what happened in Cuba. Looking at my Haiku drivers directory I zero onto the Wacom driver.
Once I blacklisted the driver my computer has been running as normal.
Hope this help someone.
Note: Theproblem is in the hardware since I have seen it in both OSes.
