Passthrough is not supported, GL is disabled

Tested environment

Windows OS, Chromedriver vesion 89, headless mode

Solution

I am not certain that this can be a solution for your question, since the error message is slightly different.

As I remember correctly, the error message Passthrough is not supported, GL is swiftshader has been shown after the Chromedriver version 89 as a bug (but not certain) [1].

In case of Windows, --headless and --disable-gpu options are required to make the chromedriver work as a headless mode [2]. It seems like --disable-gpu is also required for Linux because of the bug [3].

  1. The error message does not appear if both --headless and --disable-gpu options are removed. However, the chromedriver does not work as a headless mode anymore.

  2. In my case, the error message does not affect the operation of a headless chrome. As I found, “Normally, Chrome would just fall back to work without GPU. However, for consistent results, Telemetry requires the presence of GPU [4].”

  3. I’ve additionally applied --disable-software-rasterizer option to disable WebGL [5]. The error message does not show anymore under the headless operation.
