Launcher 5.5.4
Create a new material as the picture below or you can open my project in attached file.

Switch to mobile preview in editor and the preview flickers.
It seems to be a precision problem in the new half mode mobile preview. It works either when switching to float material expression or replacing ArccosineFast with Arccosine.

Hello,
Thank you for reaching out.
I’ve been assigned this issue, and we will be looking into this flickering for you.
We were unable to reproduce the issue as you described, testing with Generic Android Vulkan Preview and Generic Android OpenGL Preview, with the editor launching under both DirectX 12 and Vulkan.
Are there any other details you can provide to help us reproduce this issue?
Hi,
Thank you for replying, and here are all of the details:
I just created a brand new empty project with Epic launcher. Then created this material with 3 (valid) material expressions: Texcoord, Normalize and ArccosineFast.
Save and close the material and switch to Generic Android Vulkan Preview. When I opened it again the flickering came.
That’s all what I did, without modifying any settings.
I got the flickering on both my 2 PCs:
win10 21H2, 5.5.4 source build, 12700F, 4070 with 572.83
win10 21H2, 5.5.4 launcher ver, 13600KF, 3060 with 551.61
That’s all.
Hello,
Thank you for reporting this. I can confirm this issue can be reproduced as described in the latest CL, and have opened a bug report:
The tracker will be visible after it is approved internally at Epic Games and is publicly accessible.
If you have any further questions, please let us know.
