Can you please attach the Apple crash log and/or the Server Crash ID from chrome://crashes here ?

Thanks.

I’ve searched but it doesn’t look to be here( the most recent one is from october 2017)

This sounds like Chrome is causing a Window Server crash, which is quite bad. I wasn't able to repro the issue on my machine. Can you please provide:

1) GPU information by navigating a Chrome tab to about://gpu and saving the contents

2) The Window Server crash should be available in ~/Library/Logs/DiagnosticReports . Note that it's a hidden file. From the terminal, run 
"""
ls -alh ~/Library/Logs/DiagnosticReports/
"""
to see the full list of files there. 

3) After this happens, please compress and upload the file: 
"""
/var/log/system.log
"""

This will contain additional context for the crash.

 Issue 806599  has been merged into this issue.

We may want to get this into m64, given the severity.

sdy managed to get a machine to reproduce this, and got it down to the range:

https://chromium.googlesource.com/chromium/src/+log/65.0.3324.0..66.0.3334.0?pretty=fuller&n=10000

sdy, can you check if reverting r530351 on a local build causes the issue to re-appear?

Yes, I think this would be sensible to merge back to M64 if we can pin down for certain what the issue is.

Re. c#9, yep, I'm working on that now.

Disable AVFoundation on macOS <10.12

Fullscreen low power mode (which is triggered by use of AVFoundation)
is causing 10.11's WindowServer to crash.

Reverting that commit does *not* cause the crash to re-appear.

Hmm... does th blacklist that I at landed do it?

 Issue 806536  has been merged into this issue.

Adding Merge-Request-64.

A bug in macOS 10.11 causes the system to (effectively) reboot when watching fullscreen video. The fix is very low risk and I advocate merging to 64 if there are any more builds being pushed.

This bug requires manual review: Request affecting a post-stable build

Thanks for working on the fix. Can you please answer following:

1) How safe this merge is?
2) Is this well tested? 
3) Why is this needed for M64 vs waiting until M65? 

1. This is a very safe merge -- it adds an entry to the GPU blacklist
2. I'd like someone with a repro to re-verify it (sdy@ had a local repro), but I am confident this will fix the issue
3. The behavior (full crash of the system and logging out of the user when watching fullscreen video) started happening in M64 and needs to be fixed asap

There's been 6 user reports in Feedback about this Mac crash.

Chrome crashes and restarts my Mac when I watch a video (on any website) in fullscreen mode. I've tested this on Safari and it doesn't crash my laptop there.

Full screen youtube watching leads to crash mac os It's similar at any video on youtube. This issue was introducing with tle last chrome update Please fix it ASAP

Hello, Full screen videos (youtube or dailymotion) crash Mac os X (El Capitan version 10.11.6)! Indeed when I start playing a video in full screen (via Chrome), after 4-5 seconds, the screen goes black, then Mac OS asks me to enter my user password ...

on chrome when ever i play a video on full screen my macbook will crash and sleep then wake up. forces me to login to my mac i need help


mac book pro Click to maximize window The program will crash Need to force close and reopen Watching web video double-click full screen, then the same bug Uncomfortable dead quickly update it

This is fixed for me in the *current* stable, 64.0.3282.140. Which is interesting.

f8e519c1a446343d0f8200aa8817b2a9a512180f is the only commit that looks plausible to me — it was me fiddling with something that involved NSVisualEffectView. I wonder if getting the NSVisualEffectView off the screen is enough to fix this crash.

I originally reported    Issue 806536    which has been merged into this issue. I just updated to the latest stable release, Version 64.0.3282.140 (Official Build) (64-bit), and attempted to play the NSFW video I linked that caused OSX 10.11.6 to crash. I can also confirm that whatever change(s) were made, OSX did not crash when I attempted to play back the NSFW video that I reported earlier. Whatever change(s) you guys did, whether intentional to unintentional to fix the issue, it is very much appreciated!

ccameron@ - can you please confirm if this is still needed? Seems like per #21 is already fixed?

Okay, since stable seems to be stable now, let's just close this out.
