Viewport, objects snapping issue

Guys i am a beginner in Unreal engine like 2-3 days old. I am learning unreal for personal and professional work. I am facing this weird issue of snapping on my system. so things went like this I installed unreal on my laptop (windows)where it is working smooth.
But when I got unreal installed on my office system(Linux) it giving me this weird issue of snapping on viewport i mean when i try to pan or rotate camera felt like snap, zooming in out also feels like snap, when I try to scale some cube it is scaled to like infinity. even though i have disabled snapping on the grid, transform, rotate, scale snapping, and reduce the camera speed to 1.
Even all options inside advanced settings in grid snapping are Off. Also when I do rotate through right mouse button it feels like camera is getting attack or something
