Yes of course. I've not tested modern DEs because the emulator is still RV32-only, but xterm with twm works very good.
It's still works with interpreter with 1/3 of QEMU performance. With JIT (which is still WIP) it'll be even faster.

Source: I tried it on OpenBSD on a "moderm" machine (2007_ and with a medium-high load you could see redraws going on.
This never happened to me with FVWM or CTWM.
