I have a similar problem to this video:

From about 8 seconds onward, see that diagonal / cross hatched
faint pattern?

How do I get rid of it?
Can't find anything in my driver settings
(Intel 5500 integrated graphics and Nvidia 940m)

It's not noticeable from far away due to the faintness
but it can be seen quite easily close up when there's motion
on screen (e.g. gaming).

I can see this pattern easily by just moving
my eyes close to the screen in a diagonal
motion.

It sounds like I'm nitpicking but
I'm not the type to nitpick.
It's faint but noticeable
and is frustrating when gaming
especially on lighter colours.

Is there a registry edit or something?
I'm guessing other graphics / drivers
have an option to eliminate it in some way
but my drivers have few options.

Someone in the comments said they
set the "trace free option" in the "colour menu"
to 0.

I have no such option in any of my graphics settings neither Intel or Nvidia.
 
Solution
I have not looked for scaling options in the Intel control panel.

Trying a live linux cd/dvd/usb is actually a good idea to rule out a Windows issue.

Not all monitors are created equally so my first guess was the screen simply looks that way(be it by overdrive or actual image dithering[FRC is a kind of dithering that users are not supposed to see.]).
Tracefree(for Asus screens) is the overdrive settings on the monitor it self. You use the monitors Menu button to go find that.

You may also be seeing a PWM backlight(it is hard to explain). This can cause some strange artifacts for users to see. PWM dimming is more noticeable at lower brightness settings many times.

See if you have more than a single line close to each other on this test.

What monitor do you have? It is possible that you have an older screen that did in fact use color dithering. This would have nothing to do with the computer and all be done in the screen(has its own control board inside) it self.
 
Sorry I was not clear.
My problem is similar but it's on
my new laptop screen.

As far as I can see in driver control panels (Intel and Nvidia)
nothing seems to refer to or fix this issue
unless there's some way to get better drivers?

My old laptop had the snowball effect dithering sometimes in gaming
but on this new laptop the dithering is difference (worse imo even if it's subtle)
with the faint diagonal lines / sometimes cross hatching effect. :/

Not nice for close up laptop gaming. 😱
 
What do you mean by that?
Is this a software issue (incompetent drivers)
or hardware issue? (Bad screen)

I'm guessing (and hoping...)
it's just a driver thing? 😱

Does Linux have significantly different drivers / GPU control panels to Windows 10 versions?
Intel drivers.....sigh....they're so annoying.
My Intel drivers also do NOT allow me to scale games!!
So older games play with black borders. :/
