Completly Broken UMG Widgets on iOS since 5.5

[WyrdSoftware]

I have already submitted a bug report, but my report does not appear in the bug tracker. I am not sure what else to do to get Epics attention about the issue. That’s why I post here.

Since editor version 5.5.x if you have more than 1 WidgetComponent in a scene, they start flickering and switching place with each other.

I am surprised that with Epics move to “bring mobile up to par with desktop” such an essential feature can be broken without anyone noticing or caring to fix it. This has been the case since launch of 5.5 so around 3 Months as of writing.

I have tried and was able to reproduce this bug this with versions: 5.1, 5.2, 5.3.

I will post the reproduction steps below:

1. Create a new Third Person Template with the settings:
   1. CPP
   2. Mobile
   3. Scalable
   4. starter content

2. Create 2 Actors (A,B) and 2 Widgets (A,B) with a UTextBlock and different text in them. To facilitate the visualization pick 2 different text colors.
   1. Add a WidgetComponent to ActorA with Widget A as Widget Class
   2. Add a WidgetComponent to ActorB with WidgetB as Widget Class

3. Add Both Actor twice (or 4 times) to the scene, next to each other. The more you add, the easier it becomes to see the problem.
   

   

4. Build for iOS and deploy to your iPhone/iPad (add your xcode credentials)

5. Launch the app and look at the WidgetComponents, make sure they are all in the viewport.

Hey, how to make unreal mods to see this? The issue is critical! #help

I’ve been experiencing similar issues, and backporting this engine change from ue5-main appears to have addressed the issue for me.

Hi there, we are hitting the same bug here! The commit url-link is broken, any recommended temporal workaround to circunvent this problem. Thank you!

You must have access to Epic’s private Unreal Engine GitHub repository in order to use that link. Unfortunately, there’s no quick workaround—cherry-picking the changes is tedious and error-prone, so I don’t recommend it.

I’ve reported this issue to Epic multiple times, but each submission has been rejected. It seems they aren’t even aware it’s happening. This is a critical blocker for anyone doing iOS development, which clearly conflicts with Epic’s stated goal of improving mobile support.

If you’re affected, please also file a bug report here:
