What steps will reproduce the problem?
(1) Build browser_tests.
(2) Run the DesktopCaptureApitTest.ChooseDesktopMedia.

What is the expected result?

Expect that the test runs cleanly, with no process crashes or other errors.

Expect that if the test has errors (e.g. processes crash) then it fails.

What happens instead?

Sometimes the test runs without a GPU process crash, but usually the GPU process will DCHECK. Even when the GPU process crashes, though, the test will still pass.
