Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-chromium (Nobody)
<chromium@FreeBSD.org> for maintainer-feedback:
Bug 276637: www/chromium: add vk_swiftshader_icd.json to the chromium and
ungoogled-chromium package
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276637



--- Description ---
In FreeBSD, the file vk_swiftshader_icd.json is not yet delivered with the
package. This is the case under Linux and Windows.

Without the file, errors will occur in some situations. For example, if
chromium is called with the --disable-gpu switch, the following errors are
reported.

These errors disappear with the file.
