This test has been very flaky on linux-chromeos-rel:
https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=interactive_ui_tests&showAllRuns=true&tests=LoginCursorTest.CursorHidden

And it has recently started failing consistently on Linux Chromium OS ASan LSan Tests (1), since this build:
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Linux%20Chromium%20OS%20ASan%20LSan%20Tests%20%281%29/28314

Looking at the blamelist there, https://chromium-review.googlesource.com/1129384 might be related, as it also deals with CrOS login.  qnnguyen@: would you be able to triage this further?  I'll go ahead and disable in the meantime.

Sample failure output:
