Hello,
With version 1.8.4 the update introduces a brush / pick point offset. Whenever using a Wacom tablet with version 1.8.4 the brush preview may show where the stroke will be but when you begin your stroke the stroke is actually offset a brush tip size to the left. Also, if you are using a Wacom table to edit curves, you cannot actually drag and edit nodes because the pick point is offset.
NOTE: version 1.8.3 DOES NOT have this issue. Therefore, if you are experiencing this, the only solution I found is to revert back to 1.8.3.
