** Description changed: [ Impact ] On some machines, the Ubuntu logo appears to flicker between the Plymouth animation ending and the login screen appearing. [ Test Plan ] 1. Reboot the machine and stare at the Ubuntu logo while it's booting. - 2. Verify the Ubuntu logo never flickers when the GNOME login screen appears. - 3. Repeat steps 1-2 a few times to be sure. + 2. Ignore any Plymouth flickers during the black background - those are unrelated to this. + 3. Verify the Ubuntu logo never flickers *when* the GNOME login screen appears. + 4. Repeat steps 1-3 a few times to be sure. [ Where problems could occur ] The login screen logic could be broken by changes in this module. Historically that could result in effects as severe as the login screen becoming mostly blank and unusable. Make sure the login screen is still functional. [ Other Info ] Not all machines experience the bug because it is a race condition between the main (rendering) thread displaying the first frame and a background thread used to load the logo image from disk.
