I understand it’s still an unstable version.
But why is version 5.3.0 prealpha 6f434a9 so slow to navigate through?
UI interaction is not smooth and everything is delayed. What is happening?
Why?
It’s not something that happens on other systems as far as I’m aware of. So you’ll need to provide more information about your system, outputs from the system information options under the Help menu and ideally a screen recording of it happening (from before Krita starts ideally, so that you’re not cutting out pertinent information.)
Ideally, you should also try it on a clean configuration, with no custom settings, resources and in particular no external plugins installed. Those are the most likely cause, given that it’s not a problem seen everywhere.
(How to get a clean configuration on Windows someone else will have to say, I don’t know if you can run Krita under a different home directory like you can on a normal operating system.)
I tried a clean install and the issue was still the same.
I deleted the resource cache and kritarc files. But it didn’t work.
Was still super slow.
While painting there’s no problem, but once you commit your stroke, there’s a triggered
temporary freeze.
Attempt to hatch rapidly with multiple strokes and the app will appear fully frozen while
you keep doing the hatching.
Also I don’t use or run any plugin besides the native ones.
How does this go together with what you said originally? You said it is “slow to navigate through”, now you are talking about painting. Is this an additional issue or is that problem gone after reinstalling and this is a new one?
Please also follow the rest of what I said, not just one part of it. More information is needed to get to the bottom of this issue.
Not an additional issue, no.
You see, some parts of the UI are fast, like switching between some active dockers.
While other elements, like selecting a layer, creating a layer, committing many strokes,
unscrolling menus, are unbearably delayed and slow!
So it’s super weird! But It’s all part of the same problem.

Additional note :
The scratchpad is not affected at all by the issue!
Builds labeled under Krita 6.0.0 prealpha have normal UI performance and no lag,
however the click with stylus is buggy, with the interface causing the click to repeat
twice for one click.
Consequences :
- you attempt to select a menu, the menu show and hides
- you untick a brush option parameter, but once ticked or unticked, you can’t change the state,
until you click on something else, then click back again; - you can not select multiple layers with CTRL or SHIFT for some reason
I have the same problem since like, august I think, I always use the prealphas releases to work due to the new functions and for testings, but since those dates, every prealpha release worked slowly in any windows I have, in android and linux works fine. The Ui feels a little laggy and every brush lags a lot.
