Viewport stuttering during orbit/zoom navigation

Received a report of persistent stutters in the editor when trying to navigate in the viewport, including asset editor viewports like the Skeletal mesh editor and control rig editor.

Hardware used is A5000 Graphics Cards and Xeon CPUs on Windows 11. Drivers ranged from up to date (as of December 9, 2025) to up to 6 months before.

This was reported as reproducible in 5.7 but not in 5.6 even while both editors are open.

See addl info URL for more info.

Is 100% reproducible on specific hardware.

• Open the default level in a new project
• Put a cube at the origin
• Holding ALT + right mouse, repeatedly zoom in and out from the cube
• Notice intermittent camera zoom jumps when doing this
• Notice you also getting the same intermittent jumps when ALT+ orbiting
