--- Comment #26 from Peng Wu pwu@redhat.com --- If we only assign one CPU to the pango-view process, the bug can be reproduced.
Here are the command line.
$ taskset -c 0 pango-view --no-display --dpi=72 --font="Roboto Condensed, 8" --antialias=none --backend=cairo --output="out8.png" --text="ABCDEFGHIJKLMNOPQRSTUVWXYZ"
