Title:
[snap] Default ANGLE renderer doesn't work in headless mode
Status in chromium-browser package in Ubuntu:
Fix Released
Bug description:
I use a headless browser with Selenium to automate access to a WebGL-
heavy site. The current Snap package of Chromium (Chromium
97.0.4692.99 snap) running on Ubuntu 20.04.3 LTS cannot use WebGL in
headless mode.
I was able to use the same script with the Snap package previously,
but unfortunately a lot of time has elapsed since I last tried it, so
I'm not sure exactly when this issue first appeared. I believe that
the implementation of headless WebGL has changed recently, so perhaps
this is related.
I can can easily reproduce this issue in the terminal by attempting to
open a WebGL test page in a headless browser. This outputs multiple
errors:

When I ran a script to use selenium to save the output of this
webpage, it reported that WebGL was disabled. (Using the screenshot
option, which I was previously unaware of, should provide the same
result.)
I have confirmed that the identical version of Google Chrome
(installed from the .deb package on Google's website) works, and so
does a slightly older version of Chromium from a .deb package
installed from a PPA. The executables from these packages do not
produce the errors above, and WebGL works correctly in headless mode.
While searching for these error messages I found various bug reports
for similar WebGL-related problems. I noticed that some of the
suggested solutions referred to library files which are installed by
the working packages but not by the Snap package (for example
libvk_swiftshader.so).
