[Bug report] No transformation gizmos with mobile preview on

HERE IS LATEST INFO:

In 4.13.2, bug is much easier to reproduce.

  1. Launch Engine (4.13.2) and open a new blank project (with basic floor plane and sky sphere).

  2. Set to target Mobile, Scalable, No Starter Content.

  3. When project launches, click on player start. You will see transform widget.

  4. Now click Settings > Preview Rendering Level > Android Preview.

  5. You will still see transform widget, but notice preview window has NOT updated to LDR, despite Mobile HDR being disabled by default in this new project.

  6. Now click Save and save map as NewMap, then close project.

  7. From launcher, open project again.

  8. Switch Preview Rendering Level back to Android Preview again.

  9. Notice LDR now shows correctly, AND transform widget has disappeared. Additionally, scale widget shows only triangle part of it. Only Rotate widget appears normal.

Thank you for your attention to this matter.

Sincerely,
Janz
