ADDITIONAL INFORMATION

Hello. I will write here. Correct if the wrong place. I want to say that the tip of any brush looks like this if you draw lines quickly. That is, it is not sharp.
It can be sharp if you draw the line slowly.
Maybe the problem is a large number of clicks? Is there any way to fix this? This is actually very disturbing.

I add a screenshot below that shows how it looks and how I want it to look.

Hi, this is likely a peculiarity of your tablet. Tablets differ a lot in how they report pressure, and we have a setting in Krita to counteract this, namely the tablet pressure curve under settings->configure Krita->tablet settings.

Here's a (old but still very relevant) tutorial from David Revoy on how to use it:

Hi. I tried all the settings in tablet settings Krita. Nothing helped. I still have what's in the screenshot. With any settings.

Ok, if I draw really really fast I can reproduce, using the stablizer with a low smoothing amount fixes it here though, can you try?

If I do this very quickly with the stabilizer, then it turns out that I attached it under the name "2". I changed the smoothing on different strokes.

I'm only getting the result of 2 when I have 'stablize sensors' turned off.
Comment 7 LByLUC 2023-01-12 14:18:38 UTC 
If use the stablizer  with a high smoothing amount and 'stablize sensors' turned on, then it works.
Comment 8 wolthera 2023-01-12 14:20:58 UTC 
Thanks,

I'll set this to confirmed, but I don't think we can actually fix this.
Comment 9 LByLUC 2023-01-12 14:22:35 UTC 
Okay, thanks for the help.

If we cannot fix it, then let's close the report, because we cannot do much, if anything. Sorry...
