I am a Korean user using Unreal Engine.
I understand that the sentence is strange because I used a translator.
One day suddenly the viewport screen continues to move without stopping.
Pressing the ALT key will pause for a while, but I do not know how to stop it altogether.
I did not touch the other settings.
Even if you create a new project, the same symptom will appear when you delete the engine and install it again.
How do I fix it?
