screenshot of the straight lines between strokes

Hi, I am having a problem with making brush strokes in Krita. This bug did not occur at all on my yiynova msp19u+. but it is happening now with every stroke on my ugee 2150. They both use UCLogic drivers and their user interface and basic functioning is really practically identical (for the driver) so I feel this is a strange thing, that one would have this and one would not. ( I have read on the site about which tablets krita supports). So, there are straight lines between every stroke, like if the program doesn't recognize that I have lifted the pen away, and it tries to catch up. The brush circle cursor stays where it was last lifted away, and does not disappear. 
I've seen this similar issue here:

It also interferes with making a new layer or any type of click outside the canvas. It thinks I am still clicking inside the canvas, making a stroke, so no other actions are possible until I manage to make it finish the stroke.

(in krita 3.0 and 3.1 beta 4)
Also, any stroke I make at all, upon making a new canvas and using my pen on it, does not appear until I raise the size to at least 50+

I'm really hoping something can be done because I would love to use krita, it is really great. Thanks for your time!!!
let me know what you think!
