[iOS] UMG textfield crash with using Metal

Hi I experience a critical?? bug…

Test Environment

  • OSX 10.11.6
  • Xcode 8
  • iphone 5s 9.3.5
  • UE 4.14.0 (PV3 install from launcher)
  • bSupportsMetal=True in DefaultEngine.ini ( Support Forward Rendering with Metal (A7 and up devices) )

How to reproduce bug

  1. Make TestApp ( I make cpp project, just 2 text box, and 1 Button(click event with launch URL https://www.google.com) )

114770-btn0.png

  1. Launch this app With iOS Device.

typing any character with text box simply.
5. execute button and open browser app.
6. return to TestApp.
7. repeat 3~6 until crash.

crash is randomly occur when doing [3.] with virtual keyboard. (Not 100%)

I expereince this bug UE 4.11~4.14.

And there is no problem when bSupportsMetal=False.

Hello,

I was unable to reproduce this issue on our end with the information provided. I have a few questions for you that will help narrow down what issue it is that you are experiencing.

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps o reproduce this issue on our end (including any steps that may have been left out of the original post)
  3. Could you provide screen shots of any blueprints/widgets/settings that may be involved with this issue?
  • I create new project and add just 3 umg . Didn’t chnage other setting.

  • link text

  • just that’s all reproduce step. need reproducing crash video?

I was unable to open the provided project for testing. Was the project provided a clean project with no additional content?

if you couldn’t open project, make new project(4.14, test Cpp project) and copy from only content folder from that.

There is Map file, UMG widget blueprint file.

Honestly, I can not understand how impossible it is. because, it was almost clean project. it was just added blueprint, map.

I have ran several tests on different devices using the project provided. However, I have been unable to reproduce this issue. Could you try and reproduce this issue in 4.14.1 and let me know if it is still happening?

reproduce situation
4.14.1 also not changed.

Hello,

After taking a look at the video, I gave the reproduction steps another try and was able to reproduce this issue on our end.
