I don't think it's related to the other startup crash. Looking really quickly, there is no ordering guarantee between ozone::mojom::DeviceCursor and ozone::mojom::DrmDevice so it could be trying to change the cursor for a DrmWindow that doesn't exist yet? DrmThread::SetCursor() gets a DrmWindow* and calls DrmWindow::SetCursor() but that pointer would be null if the order was wrong.

Migrating from Internals>Viz to Internals>Services>Viz.

Un-cc-ing me from all bugs on my final day.

This is still happening, most recent on eve-tot-chrome-pfq-informational [https://cros-goldeneye.corp.google.com/chromeos/healthmonitoring/buildDetails?buildbucketId=8924101005966780240] while running `desktopui_MashLogin`
