Out of curiosity, does KWin do  window shadows and semi-transparence during moves and resize again when the compositor is disabled, and if so, since what version? With "again" I mean: KWin4 (4.11.22) did it, KWin 5.15.5 doesn't.

Linux support for certain (integrated) GPUs is just not stable enough to do everything using compositing (and if the WM uses compositing that means pretty much everything is drawn that way AFAIU). Issues range from glitches and flickering regions that apparently needed an refresh to black screens when activating the compositor to GPU hangs (and that's "just" with the i915 driver).
