Crash on lib.cef when windows (10) wakes from sleep (randomly)

We are using cef (using CefSharp) version 79.1.36 in our application, and several times on several computers, when the computer comes back from sleep (Windows 10 latest) - the app crashed.

Today I’ve noticed that at the same moment of coming back from sleep, another application on my computer that uses another version of cef (80.0.4.0) crashed at the same time.

I have managed to retrieve the callstack one time, for some reason the other time didn’t produce a dump file.

We cannot reproduce the issue, it happens randomly. Therefore, can’t reproduce it with the demo app.

Google Chrome kept running as usual when the issue happened.

attaching event logs from eventvwr, and callstack.

Have you tested with any other CEF versions? Did you get this crash with those versions?

Since it is VERY random (also happened ~month ago), I wasn’t able to reproduce with other CEF versions except for the 2 versions in the attached log.

Do all of the impacted machines have the the same Windows version? What about hardware configuration?

Both machines are using Windows 10 1909 (build 18363).

As for hardware, one is Lenovo T460 and one is Lenovo T470p.

I had a crash with an external screen, and one with only the laptop screen

Marking issues that we're unlikely to address as WontFix. If it still applies with currently supported CEF versions, and someone would like to submit a PR fix, then we can reopen.
