In that optical illusion it stops flickering when you stare at a spot. What happens with one of my monitors is that horizontal lines keep changing in brightness even if I keep staring at the same spot.
The worst flickering on one of my monitors happens when it has the default 100% zoom.

The subpixels on an LCD go like this:

That’s how most LCDs are, but depending on how you’re holding it, a tablet can be either RGB or BGR. Or, even worse, VRGB or VBGR, where the V stands for vertical. Some desktop monitors are BGR. I don’t know if that’s intentional, or if they just didn’t care which way the display panel is mounted.
As an aside, Microsoft’s ClearType defaults to RGB subpixels, but can readily be set to work on BGR panels. It doesn’t work on portrait displays, which would be either VRGB or VBGR.
