Common solutions used to be re-select wallpaper, but this also does not resolve the issue this time.

All my packages are up to date from updater.sh and it seems nothing errors.

Manually running matugen and choosing a color seems to work, but produces a different accent color on window borders than I was used to.

Any ideas?

usually can be fixed by setting a wallpaper again with the wallpaper icon in th eright menu

Yes this is what I indeed usually try, but it did not help this time around. running matugen manually from terminal seems to fix it, but IDK if that does the exact same as the updater.sh does when it gets there. (I assume not, otherwise it would work of course)

I have this issue as well, do you have to run matugen each time? I have to…

That should usually not be necessary no, it’s taken care of by the updater.
