UE 4.27 Touch Interface Bug?

Hey guys. I need your help.
I have been working using Unreal Engine 4.26.2 for a while, no problems. But recently I tried to migrate my project to UE 4.27 and I’m experiencing an anoying “bug”, I don’t know. It’s about touch interfaces. When I use a widget touch interface, my center thumbstick always goes to the edge, even moving the minimal possible. I didn’t make any changes, just created the third person project and activated the touch interface, I did reinstall the unreal engine, my Windows 10… But it is the same problem.

Well, I thought it was some problem in my PC, so I exported the game to mobile to test in my Android, and the problem persisted even in my smartphone! I just touched the screen to move the thumbstick and It instantly moved to the edge. I think it’s a problem with the version 4.27, but I need someone to confirm this to me. Or something I’m doing wrong… I recorded this video to you take a look.

Could someone help me? Is something I’m doing wrong or it is an UE 4.27 bug? Remembering I didn’t make any changes to the editor or project, It’s all default settings. Even reinstalling the editor, the Windows, exporting the game… the problem persists.

OS: Windows 10 build 19043
Unreal Engine version: 4.27

Same here even with a fresh new fps project on 4.27. So do not reinstall your computer for this :slight_smile: . It’s a regression.

Re,

The issue was fixed here:
https://github.com/EpicGames/UnrealEngine/pull/8382/files

You can build yourself the engine with the fix or wait for the next version (4.27.1?)

I have tested the fix myself and it’s works.
