This seems to be happening reliably on multiple focal machines: 0. Turn on or reboot the machine. 1. See the BIOS logo. 2. See a blank purple screen (grub) 3. See the BIOS logo again (this bug) 4. See the purple screen with Ubuntu logo (plymouth) 5. See the login screen I believe this is related to ACPI BGRT changes in the kernel. And I guess it wouldn't even need fixing if we just eliminated the blank purple grub screen (step 2)...
