--- Comment #17 from tanya_lug at freenet.de ---
I'm on a triple-boot Asus eee-pc 1000H (2 Mint, 1 Manjaro (intel-ucode
removed)), hope my findings can help to fix this:

This is not a kernel issue by itself but also grub issue, triggered by the
‘fixed’ kernels of the 4.13/4.14 series, both in Mint and Manjaro. In a
nutshell: If you want to boot a ‘fixed’ kernel of the 4.13 or 4.14 series via
the 2 top lines of your grub menu it will glitch, both on Mint and on Manjaro,
but booting the ‘fixed’ kernels further down the grub menu works fine.

If you then sudo grub-install /dev/sda from an OS further down the menu, the
error shifts to the new OS in control of grub, allowing the others to boot
without problem, including the one that glitched when in control of grub.

Other peculiarities of this glitch:
- clicks on the black bit are ‘getting through’ to windows below, mouse-overs
of windows below are visible on cursor icon status changes, you can ‘feel’ your
way to the title bar, drag it into the 20% and use it
- if you remote desktop into your glitched machine there is no glitch

Also, you can fix the glitch from within the glitched system, here 2 ways:
I use ‘newrez’ script to change my eee-pc resolution on the fly, 
(https://www.linux-apps.com/content/show … nt=1346861) Place newrez.sh where
you can see it, the 20% strip, run it (e.g reloading default) and the glitch is
gone (Run ‘newrez default' at startup and you can use the machine normally
without GRUB_GFXPAYLOAD_LINUX="text"). Similarly, I can fix it on my eee-pc by
running:
xrandr --newmode "1024x600_60.00"   49.00  1024 1072 1168 1312  600 603 613 624
-hsync +vsync
xrandr --addmode VGA1 1024x600_60.00
xrandr --output VGA1 --mode 1024x600_60.00
