Lot of jittering on Lenovo Yoga 730

[Takiro]

I looked through some topics and this one was the closest I could find. Issue was an out of date driver and wrong tablet settings.

Pen Pressure not working Desktop Levono yoga A940

So it’s really weird. After messing with Krita for 3 hours trying to get the pen pressure to work, you have to initiate the windows 8+ pointer input that Nayo posted and then at the bottom right of your screen (in your taskbar next to the time and date), click the notifications “action center” button (it looks like a message). A side bar will pop up, click the “tablet mode” button that’s towards the bottom of the screen and you should now be able to use your pen with pen pressure in krita. Getti…

This one is also much like yours but even more extreme

Pressure sensitivity spikes, dotted effect

Is there a way to fix the issue? I tried reinstalling the software but the problem is still there

There are many more but the solution is almost updating drivers or in this case again switching from Windows Ink to WinTab or the other way around.
