Bug: Analog/D-pad input freezes camera-look while held, flickers on release (Wine/DirectInput camera axis)

Summary
When using either an on-screen analog joystick or the on-screen D-pad to control in-game camera look, the camera stops responding entirely while the input is held down. Movement only registers in a burst the moment the input is released, and that burst causes a brief flicker between two close camera positions before settling. This affects both analog stick and digital D-pad input identically.

Key observation ruling out display/aspect theories
Menu/cursor navigation using the exact same stick and D-pad inputs is smooth and responsive with no delay. The freeze/flicker only occurs during in-game camera-look, not cursor movement — suggesting the issue is isolated to whatever input path feeds relative/raw mouse deltas to the game's camera control, separate from the (working) absolute cursor movement path.

Steps to reproduce

1. Launch a game using Unreal Engine (tested: The Vanishing of Ethan Carter Redux, Epic Games).
2. In-game, hold the on-screen analog stick (or D-pad) in any direction to rotate the camera.
3. Observe: camera does not move while held.
4. Release the input.
5. Observe: camera snaps/moves in a rapid burst, flickering between two close positions for a split second before stopping.

Expected behavior
Camera should rotate smoothly and continuously while the stick/D-pad is held, proportional to hold duration/deflection, with no flicker on release.

What I've already ruled out

• Toggled Shooter Mode (dynamic joystick) off — no change to this specific issue
• Tried XInput-only, DirectInput-only, and both enabled — freeze/flicker persists in all combinations
• Toggled "Use SDL API" on/off — no change
• Tested at both custom 21:9-matched resolution and standard 1280x720 (16:9) — identical behavior at both, ruling out display/aspect scaling as the cause
• Confirmed touch-drag based camera look (right-side touchpad) works for movement but has a separate issue: snaps to a position relative to initial touch point on first contact
• Cursor/menu navigation via the same stick/D-pad inputs works smoothly with no delay, isolating the bug to the in-game camera/relative-mouse input path specifically

Environment

• Device: Poco F6 (Snapdragon 8s Gen 3, Adreno 735)
• GameNative version: [1.1.0]
• Container variant: Bionic
• Wine/Proton version: proton-11.0-1-arm64ec-1
• Game: The Vanishing of Ethan Carter Redux (Epic Games, Unreal Engine)
• Renderer: DXVK
• Controller Controller-tab settings at time of testing: SDL API ON , Enable XInput API on, Enable DirectInput API on, Shooter Mode off

Additional notes
Would be happy to provide logs, let me know what's needed.
