Lines appearing outside the canvas area

[Stefan Cargoski]

Hi community. 

I just bought a new PC monitor, and Im seeing line appearing outside the canvas area, both in PS and AI.

What could this be? is it a known Adobe glitch or is it my new monitor? Im a bit worried..

Kind regards.

Go to Preferences > Technology Previews... and check "Disable Native Canvas" - then restart Photoshop. Does the problem still occur?

Hello

I dont have this option to "Disable Native Canvas". This is what appears in the Technology Previews:

I got the same exact monitor, and the lines dont show up, so its obviously a fault of the monitor.

Kind regards.
