Description

Seen on several tests, intermittently: the screen turns black (leading to failure to find reference images, like GnomeApplicationsMenu.png).

This includes at least persistence.feature, untrusted_partitions.feature (also seen with others, but I initially thought this could be some rare glitch).

Trying to attach to the TailsToaster VM through virt-manager, and trying to send various Ctrl+Alt+Fn doesn’t lead to any changes.

I’ll try disabling the snapshotting mechanism to check if we can get more reliable (even if longer) runtime.

Bumping priority as snapshots are a very important optimization of our test suite.
