How do I prevent the GPU process from being launched?

[rroy]

I have tried to disable accelerated compositing and webgl both programmatically and using command line switches but the browser process is still launching a process with type=gpu-process. Here is the complete browser setting:

CefBrowserSettings browserSettings;
browserSettings.accelerated_compositing = STATE_DISABLED;
browserSettings.webgl = STATE_DISABLED;

// the other settings used are:
browserSettings.plugins = STATE_DISABLED;
browserSettings.java = STATE_DISABLED;
browserSettings.javascript_close_windows = STATE_DISABLED;
browserSettings.javascript_access_clipboard = STATE_DISABLED;
browserSettings.javascript_dom_paste = STATE_DISABLED;
browserSettings.local_storage = STATE_DISABLED;
browserSettings.databases = STATE_DISABLED;
browserSettings.universal_access_from_file_urls = STATE_DISABLED;
browserSettings.web_security = STATE_ENABLED;

I am also providing the following command line switches when launching the CEF process: "--disable-accelerated-compositing", "--disable-webgl".

Use the --disable-gpu flag.

Use the --disable-gpu flag.

Tried that as well without success.

You should not include the "--" prefix when setting the flag in the OnBeforeCommandLineProcessing callback. Read the documentation in the header files.

[rroy]

I did not use the callback. I passed the arguments as command line arguments when launching the process. Is that wrong? In any case, only setting the CefBrowserSettings should also work, right?

What CEF3 version are you using? Newer CEF3 versions use "--disable-gpu" and "--disable-gpu-compositing" command-line flags.

Hi Marshall,
I am using 1916.

I have tried launching the browser process with "--disable-accelerated-compositing", "--disable-webgl", "--disable-gpu" and "--disable-gpu-compositing" without success. I have also tried loading the simplest content possible (http://www.example.com) just to exclude the possibility that the HTML content is triggering the GPU process. But the gpu-process always gets launched. Is this a bug?

Is this a bug?

It's complicated. Newer Chromium versions require a GPU process for compositing in both the browser and renderer process (even when using software compositing) so not having a GPU process may no longer be a tested/supported code path. See also https://groups.google.com/a/chromium.or ... By_So7zokJ for more (potentially out-of-date) information.

Last thing to try is the "--in-process-gpu" flag.

is there some switches like "--in-process-utility" ?
