It does that only for fullscreen gl, not for window mode. Also it
doesn't do this for fullscreen if I use "expand=1920:1200" filter.

It's normal libass 0.10.0, don't know what can be wrong with it..

Anyhow you don't need to debug libass blur issues - there is example
where there is no karaoke, but fullscreen rendering still becomes very
flow, that is, gl-window-nokaraoke and gl-fullscreen-nokaraoke.
