Edit: This is apparently due to a new Kalpa theming. Hence it only affects Kalpa.
OK, this is strange. On my work laptop running openSUSE Kalpa (aka immutable Tumbleweed) the KDE window decorations are messed up.
The buttons to close or minimize the window are now on the left.
The buttons for the window menu or pinning a window to all virtual desktops are now on the right.
I do not find any setting in the KDE system settings that would change that.
Everything else is as it should be, i.e. no right-to-left language or anything else I can think of.
All other laptops running Tumbleweed seem to be unaffected.
Any ideas, anyone?

Finally got around to giving #Gentoo #Linux a real try again 🐄.
I postponed that because it would make my laptop unusable for several days, but then I figured that I could simply bootstrap it into #btrfs subvolumes from my #openSUSE Tumbleweed.
I now have two distributions in the same LUKS container and filesystem and it works great 🎉!
