--- Comment #8 from new.plan4...@fastmail.com ---
I am seeing this same same crash multiple times under the new
BlurEffect::blurRegion using kwin-wayland-5.27.4.1-1.fc38. I cannot
deterministically recreate it, but it usually occurs when opening a new window.
Every time it takes the entire wayland session down, which is incredibly
disruptive
