Caused by 262844@main (bug#255258)???
Comment 2 Fujii Hironori 2023-04-12 21:10:27 PDT 
This is reproducible with WinCairo Debug on my PC.
I confirmed reverting 262844@main fixes the flaky failure.
Comment 3 Chris Dumez 2023-04-12 23:14:51 PDT 
Ok, I can investigate tomorrow. Hopefully I'll be able to reproduce.
Thanks for the heads up.
Comment 4 Chris Dumez 2023-04-13 08:57:43 PDT 
I can reproduce the flakiness locally. I am debugging.
