this is neither a function nor a setting or option, this still is a graphics error suppose coming from Your graphics card and graphics driver.
See several psots here concerning the same issue.
Update driver, change graphic setting to card driven, software driven, and so on, till this bad lines will not occur any more
Most obviuos help will be a change in graphics
Thanks, I have this problem just in Solid edge (Skatching). in other softwares and in Windows I do not have this problem.
Even in solid work in 3D mode I do not have this problem just in sketching in Solid edge it happens.
You are right, Thanks a lot. the details for setting are:
fine so far, but if possible try to enhancde the hardware use of Your graphics card step by step.
Software driven is the slowiest method of showing Your model.
If possible to have the g card in use would be better.
As said maybe You have to update the driver first
