_______________________________________________________
Details:
Affects: Grub version 2.04 (Debian)
Description: After Cold-Booting PC Bios/Uefi screen is displayed correctly,
but when Grub2 is loaded and displays menu the entire screen become garbled
and unreadable. This looks like as a cosmetic problem as in other aspects all
works, you still could change boot parameters or change which entry to boot
etc. Then immediately when Linux is booting (or windows) from this state the
screen is again displaying correctly and text is readable. What is even more
strange, after rebooting the grub is displayed correctly without any
glitches.
Reproducibility: I've tested it on multiple main boards and combinations and
looks like it only occurs when Dell-monitor is connected on my AMD graphics
over DisplayPort cable. Unfortunately I do not have second monitor with DP or
second cable to test if the problem is caused by cable itself, but GRUB is
only one who causes screen to misbehave.
Grub settings are distribution-default, I haven't changed anything.
