Rss feed android 15 issue

I just recently got myself a new phone and moved over my old config. Everything works fine but the rss feed is weird. Ive set it up that i have multiple providers. When i click the left or right arrows the next feed pops up. This worked flawlessly on my old phone. Now on this phone instead of just switching between the feeds in an instant the screen goes black for a few seconds. Sometimes it doesn’t go black but then i have weird visual artefacts instead of the text. It does that for a few seconds and then shows the new feed.

I copied over all klwp settings from my old config. Tried to change the refresh rate from default to 60 or 120 but the issue stays the same.

Any idea what I could try?

If you have visual artifacts in KLWP try settings “parallel rendering” to OFF in the advanced settings
