This sounds more like a hardware problem then a LibreOffice/software
problem.
Some manufacturers have built in hardware diagnostics, run them if
available.
If you have the ability to add a external monitor to the laptop.
Although it varies from *laptop* to *laptop*, some can turn on the
*external monitor* by hitting the *Function Key* (*Fn*) plus the F5
*key*. On the *Toshiba*, continually hitting *Fn*-F5 , skips between
the various *monitor* options including *screen* duplication and
*screen* extension.

This information can be confirmed from your laptop owners manual.
If you have the ability to create a Linux OS disk like Ubuntu, boot it
and see the screen problem goes away. This may help to confirm a Windows
driver problem.

It also will allow you to do a memory check.

Go to a different computer and look for search engine listings of your
laptop model having similar problems. Youtube videos can tell you a lot
about what may be happening.
Google "YouTube Toshiba vertical banding"
Hope this helps.

I've been encouraged to post here re: my hardware travails!
Here goes...
I booted up my older Toshiba laptop running Windows 7 which for years had
been working fine.
Then, one day I booted up and got these vertical color bands where you
couldn't see anything else bu the bands.
I then re-booted and opened Word 2003 (as Libre Office take a longer time
to open and the laptop would just shut Word
down, then when I re-booted it would shut the laptop down while I was
writing in Word.
Then, I tried opening Libre Writer and it just froze – never opened so
I had to press the power button to re-boot.
I moved the laptop power adapter from the power strip to the UPS then
moved the laptop so it’s connected directly into a wall outlet in
another room. Still no good. I then powered the laptop in an outlet in
the top outlet (not the bottom one even though the last testing showed
the outlet (top/bottom)were both fine.
I then brought the laptop to work and got the same results when trying to
run it.
Someone said I might have to delete all my video drivers and r-install them.
I have no idea where to find those drivers on my laptop, nor which ones to
delete nor where I would find the correct replacement video drivers nor if
that's even a correct solution.
I've got 3 GB Ram running.
It's a nice 17" screen so I don't want to toss the laptop and it ran for 3+
hours at a friend's work space - with 4 programs open at the same time -
Publisher, GIMP, the Brave browser running a YouTube video and another
program to test the laptop and it all worked fine.
Thanks for your thoughts/ suggestions.
