Faulty view

Hi all,

I've been searching on the web for a while but couldn't find an answer.

Is a problem other than video card and updates? (or is this a setting?)

Is there any other living in this problem? or is there a name for this problem?

Thank you in advance for those who share their ideas.

English is not my first language - If you point out my mistakes I'd be very grateful..
