Distorted picture in games?

A slightly distorted picture has been seen in games on the PC for a long time. Even in Minecraft, you can see strange lines on the outside edges of the blocks. To the best of my knowledge, I updated the driver, but nothing has happened.

These strange lines could be caused by the fact that "anti-aliasing" was deactivated in the graphics settings during an update, take another look at your settings and do anti-aliasing to SMAA or something else.

Many thanks for your response. Is anti-aliasing pre-installed on every PC or how do I find it.

This is available in every game in the settings, just go to the options in the menu of a game.
