OK, on my home laptop the crashes and kwallet prompt don't happen. So I've obviously broken something on my work laptop. Anyway, regarding the logout effect, I see in the 5.7 -> 5.8 changelog that it has been dropped (https://www.kde.org/announcements/plasma...ngelog.php -> KWIN section: [effects] Drop the logout effect.) - that's a pitty since it was a really cool effect from my point of view. I'll mark this as solved, since it's definitely problem on my side.
