Well, this sounds like a crucial clue, doesn't ;-)

Please try whether the problem holds only for GL compositing or also
for XRender, and in case it's only GL you should specify the used GL
backend (GL, GLSL2, GLES) and check whether "LIBGL_ALWAYS_INDIRECT=1
kwin --replace&" behaves "better" - but iirc the OpenGL support in VBox
ain't that great anyway?!
