Hello,
I have this issue, while loading project I was working on for a while. It opens normally, but seconds after opening, this is happening to my landscape shape. It started appearing after I updated this project from version 5.03 to 5.7. At first I ignored it because it didn’t interrupt my work, but now it reappeared after many hours of working on it.
Can someone tell me why is this happening, and what shoud I do, to stop it? I’m new to Unreal, and I’m still learning how to use it.
