Passthrough is not supported, GL is swiftshader

Postby ValentinNikin » Fri Jul 23, 2021 2:12 pm

I use CefSharp to render frames from some uri.
When mode is offsreen, and disable-gpu is true, I got the ned error in the log
[0723/214625.446:ERROR:gpu_init.cc(440)] Passthrough is not supported, GL is swiftshader

Could someone know about that problem?

Other than an error in the log file are you seeing any actual problems?

If you've disabled GPU acceleration then swiftshader will be used for webgl. The error is likely safe to ignore.

Hello, amaitland!

Thanks for the reply. No other problem unless this error in logs

Unless the error manifests in a problem I'd be inclined to ignore it.

Looks like there is an open issue at https://bugs.chromium.org/p/chromium/is ... ader&can=1

Whilst the issue is for Linux, it's likely a similar cause for Windows.
