Description Tobias G. 2024-02-08 22:29:35 UTC

SUMMARY
When switching the theme of Plasma, it's done in a choppy way and there's no smooth transition


STEPS TO REPRODUCE
1. start settings
2. switch to other theme
3. observe

OBSERVED RESULT
The theme is switched in "multiple steps"

EXPECTED RESULT
The theme should be switched in one go and be smoothly animated

This is something Ive seen for a longtime (since 2021). Probably longer. The effect may be more difficult to fix than what it looks. Curious to hear what more knowledgeable members have to share about this.

We have a mechanism in place - see changing the colour schemes. The problem with lnf files is they reload all of kwin which breaks the effect.
We'll do that in due time. 

Once we fix kwin's config to be more specific this should "just work" quite smoothly.
