Partial blur only works when stencil buffer bits are available. There's
currently no way to get decorations blurred but not the shadows without
a stencil buffer.

Blur plugin should output something like "No stencil buffer, region
based blur disabled" if this is the case. There seems to be some other
drawing artifacts in your videos, which might be a bug that is exposed
only when stencil buffer bits are not available.
