Description

When you set bShowMouseCursor to false in a Standalone or packaged game while Default Viewport Mouse Lock Mode is set to either Always Lock or Lock on Capture, the cursor will become locked in place. This can be worked around by setting the Default Viewport Mouse Lock Mode to Do Not Lock but also allows for the cursor to leave the window.

Please note that this is specific to 4.14 and currently does NOT occur in 4.15 but should be considered for a 4.14.1 hotfix.

Regression?: Yes
This did not occur in 4.13.2-3172292+++UE4+Release-4.13
This does occur in 4.14.0-3195953+++UE4+Release-4.14
This does NOT occur in: //UE4/Dev-Main/ CL# 3200526

Steps to Reproduce
  1. Create a new project based off the Top Down template
  2. In the level blueprint, recreate the image attached below
  3. Play the game in Standalone Game
    Result: When Set Show Mouse Cursor executes, the cursor will become locked in place, as shown by the green decal
    Expected: The cursor should not become locked
