Weird lines appear while in editing mode (2.8)

Hey, I’m using 2.8 for a while now. I used it at home with no problem, but when I opened it on another pc, weird lines (like edges) appeard (only in edit mode). First I though it was some triangulate or something, but it is not. It appears on all objects. I’m adding a screenshot. Lines are not at fixed place, they are changing angle with angle of my view.

Since it doesn’t appear on my pc, even on my 7 years old laptop, I think it must be something with this pc, where the problem appeard. Do you guys have any idea?

Does this always happen?

What are your system specs?

please update your video card driver then try it again, may you good luck.

It happed only on this pc, I can’t tell what really is in that pc because it is school one :confused:

That may help. Thanks.
