Horizontal lines

I cannot use kicad because that shows on everyu Kicad version I install.

I would try in Preferences-Schematic (and others)-Display Options-Rendering Engine and in Common Antialiasing but it is only a guess.

This behaviour is common for old graphics drivers, often on intel-processors with integrated graphics GPU.
Try to update to the latest available drivers (look on the manufacturer-site as well as on the intel-website). Most people were able to solve the problem with new drivers, only on some systems the issue could not be solved.

The other (already mentioned) option is the set the rendering-engine to “fallback graphics”:
Preferences–>Schematic Editor–>Display options–>Rendering Engine–>Fallback
(do this also for all other editors)
