Bug ID: 430829
Summary: Pen lag / latency when on ChromeOS (Google Pixel Slate
i5)
Product: krita
Version: 4.4.2-beta1
Platform: Android
OS: ChromeOS
Status: REPORTED
Severity: normal
Priority: NOR
Component: Brush engines
Assignee: krita-bugs-n...@kde.org
Reporter: lafreniere....@gmail.com
Target Milestone: ---
Although the new Krita for Android on a Chromebook is very usable, there is
significant lag when using an active stylus as compared to the best apps
available.
For some reason, MANY art based programs have lag issues when it comes to using
the stylus. BUT there are two examples of software that has practically minimal
lag.
https://canvas.apps.chrome/ is a web based PWA made by Google. When drawing in
this program, the lag is incredibly small. It feels practically non existent.
https://www.squidnotes.com/ this Android app is not an art based program but
for note taking. Regardless, it has achieved similar latency as the Canvas PWA
by Google.
Both of those examples are the best with pen lag. My wife, a fine arts major,
art teacher and avid home artist loves Krita now that it's available on
ChromeOS. But watching her draw on Krita vs. Canvas is night and day. She loves
all the extra functionality of Krita but sadly the pen lag is a pretty big
issue. Canvas on the other hand has no pen lag but severely lacks in features.
Squid is just a note taking app, but it's an example of an Android app achieve
no lag.
So the question becomes, is it possible for Krita to have this level of lag?
Squid proves that Android apps can achieve this... Canvas, although a PWA, also
proves this. It would be awesome if Krita could have reduced pen lag matching
those.
More than happy to do any testing required.
Merci.
