Description

I watched the embedded video over at https://www.themooltipass.com/ and then my whole system froze. (Couldn't even switch to a different tty)

Steps to Produce

  1. Go to https://www.themooltipass.com/
  2. Watch video

Actual result:

System froze. On reboot I ran journalctl -b -1 and saw this error:

It seems I have disabled crash reporting... sorry.
I will enable it from now on

@rhysperry111 does this happen every time? If so, with crash reporting enabled, please visit the page and then send the report 😄 If it doesn't happen every time, we'll need to dig in more to find the root cause (since it would likely affect other sites also)

Annoyingly, I can’t reproduce the crash.

EDIT: Accidentally closed issue. Could you please remove it from completed

Update

This crash happened again with the same effect as last time - system became totally unresponsive and couldn't even change tty.

Additional notes:

  • Audio kept on playing when system was unresponsive
  • Crash happened as I was trying to make the video fullscreen
  • Still not reproducable

Crash log

I went to brave://crashes but even though crash logging is turned on it says there are not reported crashes.

I currently have the system setup to discard coredumps. Would it help if I turned coredump saving back on and then uploaded the coredump if I see the crash again?

@rhysperry111 can you please try visiting brave://flags/#enable-oop-rasterization and then DISABLING this flag?

I'm curious if this makes a difference

Just did that but will not be able to confirm if it fixes the issue as I can't find a reliable way to reproduce it

@rhysperry111 awesome thanks! Let's just watch it for a bit, let us know 😄 If that is the problem, I am working on a revert for that (as it does cause a problem for other users) with brave/brave-core#4318

Update: I haven't experienced any fatal crashes with that flag set to disabled.Can't tell if that did fix it as I did not have a reliable way to reproduce it but it seems to be working

@rhysperry111 great, thanks for the update! I'll close this issue for now... but if crashes happen again, please re-open or leave another comment here 😄 Thanks!

Going forward, this will be disabled by default starting with version 1.3 (due ~Feb 4th)

I apologize in advance if this is the wrong place to post this for whatever reason, but this is the only bug report I was able to find anywhere that described the same issue I've been having.

I am also having the same issue. I'll open a new issue as there seems to be no response in this one.
