Hi, fortunately this issue has only occurred once for me, so there isn't really any "trouble" to "shoot". If I go through all the usual steps (like re-installing drivers etc.) and then the issue does not reoccur, we'd have no way of knowing if it would not have reoccurred anyway....

Three separate users in this thread, all experienced kernel panics saying "Preemption level underflow" along with "BSD process name corresponding to current thread: WacomTouchDriver".

I just experienced exactly the same issue. My 2016 MacBook Pro spontaneously shut down, and after rebooting, it reported a kernel panic "Preemption level underflow" which also says "BSD process name corresponding to current thread: WacomTouchDriver" (details below). I thought it ...

The pointer motion is completely smooth, as it should be :-) Interestingly, the new driver does NOT add the new comp...

I just had the same experience, except I'm running macOS 10.14 Mojave. ⋅ Updated from driver version 6.3.37-3 to 6.3.38-3 - straight away my pointer became juddery and jerky, jagged and flickery, severe reduction in fps, lack of precision, totally unusable ⋅ Downgraded driver bac...
