79.x Exiting GPU process due to errors during initialization

[user6294]

Hi

58.x => 79.x upgrade

App similar to CefClient

We run with 'disable-gpu', 'disable-gpu-compositing' flags set in OnBeforeCommandLineProcessing(), and this works fine in 58.x

In 79.x, I see this in dbgview

// the -type other process exiting
[PID 20412] [0618/114157.456:ERROR:viz_main_impl.cc(180)] Exiting GPU process due to errors during initialization
// the browser host process reporting that the -type other process exited
[PID 22248] [0618/114157.476:WARNING:gpu_process_host.cc(1213)] The GPU process has crashed 1 time(s)

and the main browser host processe that called CefExecuteProcess() returned 4

// CefExecuteProcess() returned 4 (called from main browser host process 22248)
[chr.16184; 2020-06-18 11:41:57.458031; WinMain#166; INFO ]: this (parent) process will exit [PID 20412] CefExecuteProcess() returned exitCode = 4

All our processes are starting up correctly and stable. And I can quit correctly/gracefully.

Do I need to be concerned about this (i.e. will there be a knock on effect later - that I may not be aware of)

Thanks very much

What OS? Does the problem reproduce with the CEF sample apps?

Windows 7 Pro-64bit latest, no it doesn't generate the same error message

cefclient.exe --off-screen-rendering-enabled
or
cefclient.exe --disable-gpu --disable-gpu-compositing

yields this:

How does it behave if you run cefclient.exe with no flags, or `cefclient.exe --off-screen-rendering-enabled --enable-gpu`?

Are you using off-screen rendering in your application? Why are you disabling the GPU?
