Thanks for filing this! Quick question: is attachment 9670629 [details] the file you meant to link in the STR? The crash report looks like it came from a local file where a worker draws canvas text, and I couldn't get that testcase to crash on Ubuntu 26.04.

Could you also attach the output of this from the Ubuntu 26 machine?

fc-list : family capability | grep -i silf

Hello! I apologize; it seems that I pasted the wrong link. This is the correct one: https://bugzilla.mozilla.org/attachment.cgi?id=9659657. I am also attaching the test case. Note that this does not crash on Nightly.
Unfortunately, the command returns nothing for me. I also tried to save the output to a .txt file, but it's empty. If more information is needed, please let me know. Thanks!
