Software rendering was added in a79827a.
It accidentally removed the different GL initialization for secondary views (which need to copy the contents from the primary view). This is not a heavily used feature yet, as multi-window support is still in progress. This secondary codepath is in the process of being removed by #170045

It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.

test-exempt: only affects pixel output of GL rendering, which we don't have a mechanism to capture.
