I tried to install new Kicad few times. It seems still see green lines after opening the main project file (extension: *.kicad_pcb). It used to work smoothly with earlier version of Kicad software but with new version not able to open the file to see it properly. It shows many green lines and not sure where the root source of the issue is. Tried to update the image itself (screenshot).

Are you using the integrated GPU of an Intel CPU? This seems to be caused by a bug in outdated intel graphics drivers. Try downloading the current version for your hardware.
What hardware are you using? Is this a laptop or a desktop? Which CPU model? Do you also have a discrete GPU in your system?
This topic is becoming half a year old now, and the links to gitlab are now pointing to closed issues, so apart from updating graphics drivers you should also make sure you’re running the latest stable KiCad version
