Viewport Controller Camera Control Regressions in UE5.8

In UE5.8 it appears some changes were made to the camera control and navigation in the editor viewports.

You can no longer use controller and mouse simultaneously to control the camera. Previously you could use the left stick on the controller to control forward/back movement and use the mouse with RMB down to control the rotation and get nice smooth flyby controls. Now if you use the mouse the controller inputs stop being considered.

Also there is some kind of change the update or tick rate for the camera inputs and or movement/rotation. It feels like 24fps compared to the nice smooth feeling previously.

You can try setting Gizmos.Version 0 to compare to previous behavior.

Steps to Reproduce

Open the editor.

Click into a viewport so controls are active in there.

Use the Left Stick on a controller to move the camera while simultaneously using the mouse with RMB held to control the rotation of the camera.

Notice that with 5.8 the Controller input stops being considered when Mouse RMB input is applied.

 

Also notice that with strictly Controller Input the Camera movement and rotation feels like it is updating at a reduced rate. Feels like 24fps or something.

 

in Command line set Gizmos.Version 0 and notice that both of these issues go away. Now controller and mouse can be used simultaneously and the movement and rotation rates return to previous buttery smooth behavior.
