Hey bad news, I just hit this crash again today after upgrading to 2.39.90. I'll attach an all-threads backtrace but it shows cairo_ft being used on both the web process main thread and at the same time on the lone Nicosia painting thread, so it seems that using one painting thread was not as safe as you had hoped.
