time_win.cc fatal error

Postby andpad » Wed Apr 18, 2018 6:22 pm

I upgraded to the latest build (cef_binary_3.3325.1758.g9aea513_windows32). In debug mode, cefclient goes to a blank screen soon after launch. I see the following fatal error in the logs:
[0418/155224.505:FATAL:time_win.cc(621)] Check failed: IsSupported().


Using Windows 10 and VS 2013.

Any help is appreciated. Thanks.

Looks like you're failing this check: https://cs.chromium.org/chromium/src/ba ... mium&l=649

What is the symbolized call stack? What is your CPU hardware?

I'm running a Windows 10 VM on my MacBook Pro using Parallels. Windows is set up to use 2 processor cores.
My MacBook Pro has a 2.8 GHz Intel Core i7 processor.

Sounds like your VM doesn't support Windows high-resolution timer.

Thanks for your help.

Do you happen to know how this would impact a user running a release instance of CEF on a setup (perhaps like mine) where the high resolution timer is not supported? Just trying to figure out how big of a problem this is.

You might see greater variance in anything that depends on timer accuracy (rendering, etc). How does the Release build behave in your VM?

My current plan is to play and test with cefclient before doing the work of integrating this cef build into my current project (which is currently using binaries from cef_binary_3.3163.1671.g700dc25_windows32).

I've only been using and observing cefclient since this morning, and so far I haven't seen a noticeable difference.
