QA

Observation¶

When in a session on meet.opensuse.org, e.g. https://meet.opensuse.org/suse_qa_tools and I share my screen then shortly after the tap crashes with an error message "Error code: SIGSEGV". Reproduced by tinita, also in embedded jitsi sessions in workadventure.

okurz: 2024-07-12 reproduced while sharing screen and joining in parallel with Firefox, switching between windows so that also the google chrome session was sometimes in the background and not visible in an i3 session. Eventually the Google Chrome tap became unresponsive and some seconds later crashed and shows the reported error message. coredumpctl also shows the error. stacktrace available. Trying to reproduce with no other person joining. 2024-07-12 07:45Z-07:55Z no crash with just sharing screen and no other attendee and not showing own share preview in full. 08:00Z switched to look at what I am sharing myself. 08:20Z no crash. hypothesis: depends on other participants.

Expected result¶

• chrome/chromium tab shouldn't crash with SIGSEGV
• https://coremeet.workadventu.re and https://meet.jit.si/suse_qa_tools do not show this problem.

Steps to reproduce¶

• In Google Chrome go to https://meet.opensuse.org/suse_qa_tools , join the session. share the screen, wait for some minutes, observe the crash

Further details¶

• https://github.com/jitsi/jitsi-meet-electron/issues/361 from 2020 mentions "Segmentation fault sharing the screen" which seems to have been an incompatibility of older electron+chromium versions fixed long time ago already
• https://github.com/jitsi/jitsi-meet/issues/13250 is about "sigill / sigsegv on chromium and Firefox" with no proper resolution and not mentioning screen sharing as the trigger

Workaround¶

• Use a different browser to share screen, e.g. Firefox, or a different Jitsi instance
