Yes, discards are active indeed. Did you explicitly configure it (in /etc/crypttab)?
I use the kernel argument `rd.luks.options=discard`. Nothing else. The one thing that differs from a modern default openSUSE set-up is that I use the classical non-encrypted boot partition (as one would do with a BIOS boot, but I EFI-boot). Only root and swap are on the encrypted device.
