related?)
Product: krita

Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal

Assignee: krita-bugs-***@kde.org

If I draw many straight lines in a row with thin pencil brush, they are a bit

Hi

Does it's also exists in Krita v2.9.11 or does it's a regression in v3.0 ?

Hi, is this still present on 3.2.1 or 3.3.0-rc.1?

I doubt this is related to hidpi, could be tablet or driver. Were you testing
on all the systems with the same tablet and driver?

Hello.
Unfortunately, currently I do not have access to that HiDPI laptop to check.
I'll write here if any news.
