Hello This is my first time using Krita I installed the latest version
unfortunately, when using the brushed I was surprised that the draw differently from what they intended to draw
instead of straight lines curves are drawn on the white page
I don't know what's the problem
all the brushes draw the same curves with different thickness
think u for reading if u could lead me to a solution think u

Hi again

Sorry but the problem seems to concern the pen I am using

if I use the mouse everyting is Ok and fine
but if I use my digital pen Huawei everything seems to go wrong
any suggestions other than buying a new pen?

Is this a Huawei media tablet running Android?

Can you give more details such as the version of krita that you are using, the operating system and what sort of computer you're using?
What is the type and model of Huawei digital pen?

Can you provide a screenshot (or photograph) of the problem you're having.
You can post an image to Imgur (or similar picture sharing website) or use your Dropbox or GoogleDrive account and post the download link to it here.

Ok
The laptop am using is Lenovo Yoga
The pen is Huawei
And i am drawing directly on the screen since its a touch screen
I had no problems what so ever with other drawing software but i was surprise that the pen functioned like that in krita

If you're using a laptop then you'll be able to take a fullscreen screenshot that shows an example of the problem you're having and then you can post a link to it here.

I have disable touch screen by finger and adjusted the wacom pen setting (pen tip sensitivity to firm) problem is solved i get straight lines however the pen tip is not matching the cursor on the screen (if I draw a line it goes somewhat far a bit from the place i indend to draw

The parallax problem that you describe is common to combinations of display+stylus. It may be worse for a pen that is not 'matched' to the display. I don't know anything about your computer or your pen so I'm speculating.
Is there any offset adjustment or position calibration utility as part of the pen control and setup application?

My personal opinion is that you'd get better results and have a more comfortable experience if you use a drawing tablet such as one of the cheaper Wacom or Huion tablets, e.g. the Huion HS64 or the Wacom Intuos 2018. They both make better and more expensive tablets but the lower priced models are good quality.
