Brush blotches on multiple strokes

[spacecat]

I am using a Wacom (One by Wacom) tablet and I do a lot of shading and hair strands, one thing I've been battling with both designer(pixel persona) and photo are these random hard strokes or dots when I start a stroke, I usually let it go and just ctrl+z or erase but now it's getting my nerves. 

I check my wacom tablet for any issues and could not find any physical issues. Also tested with Krita with no issues (attached), seems to only appear in Affinity.

Hi spacecat,

Thanks for letting us know - I've passed this onto Development to look into.

Hello @spacecat

Maybe my suggestions help.

Open the Wacom Tablet Features 
Add the Desinger to the application list. Then click on the Pen tab and set the slider at Double-click distance of pen tips to off.
Click on the Projection tab. For Screen area and Tablet area, select Full, mark Force proportions and Use Windows Ink.
In Affinity Designer go to Preferences --> Tools and set the Input Method for Graphics Tablet to Windows Ink as well.

@komatos: I tried it again using those suggestions and noticed something in my settings.. The Affinity designer was set to *Tablet Input Method : Low precision ...

I do not know if 'Low precision' was the default, I doubt I'd set it like that. Could this have caused the harsh dots? or was it the double click? I don't know. I'll sketch some more and do some tests. 

Setting that to High precision or Windows Ink seemed to have worked, my brushes are better too. Although I'm not sure what 'Windows Ink' actually does

Hi spacecat!

"Low Precision" is default. "High Precision" crashes Af Photo in my case. What "Windows Ink" does - I don't know. As far as I know it is a software or sort of software suite from Microsoft that enables some apps to be operated with a stylus. Part of this are apps like Sticky Notes and Screen Sketch, but you can even add apps from the MS Store. Think the software suite can't be meant in this case, but possibly its engine or so. Haven't really tested it, but the strokes I draw with it some minutes ago looked good. But I can't say that they look better than "Low Precision", that are also satisfying in my case.

I see, that could explain why affinity defaulted to low precision. But I couldn't draw better curves with it turned on, plus those artifacts I keep getting. And all this time I've been using low precision.. no I wonder I struggled and blamed my wacom at first lol

There is a good explanation here:
