Why do I get these squares? Sometimes when I use a brush, this one when I used Color Range it just lots of pixels.

My PS version: Adobe Photoshop Version: 21.0.2 20191122.r.57 2019/11/22: e3e4068e635 x64

Thanks in advance

Hi Mikael,

The squares are known as artefacts and they appear either due to a bad graphics card or bad graphics drivers.
Could you please try deselecting "Use Graphics Processor" located in Photoshop's Preferences > Performance, then relaunch Photoshop and let us know if it helps?

Also, you may try updating the graphics drivers from the manufacturer's wbesite and see how it goes.
