Problems with certain devices using Vulkan API

Driven · Jul 30, 2018

Anyone else has problems using Vulkan API? On several devices like xiaomi 4x, lg x venture, lg v 20 and even sometimes samsung galaxy s7, google pixel XL (probably even more) The game just shows a black screen and nothing gets rendered except some UI and then it just freezes. Changing the API order from vulkan first to vulkan last, makes everything normal.

It's happening in All Untiy version from 2018.1 onwards.Unity 5 works fine with Vulkan except of some edgecases with multiple cameras where some sprites are just shown as a glitch desaster.

aleksandrk · Jul 31, 2018

Does it output any errors to the console?

Driven · Jul 31, 2018

Unfortunately I don't have these devices by myself to catch the logs, it was always try and error with the users until it worked by removing Vulkan.

What's funny is that sounds and game logic seem to work but the the game is visually not there.

I have submitted a repro project some time ago but still no response so far except that the project was too big with first submit.

aleksandrk · Jul 31, 2018

Can you post the bug number here?

Driven · Jul 31, 2018

Case 1044679

Driven · Sep 17, 2018

@aleksandrk any news on this? It's still not working with 2018.2.8f. Game just does not start with Vulkan API, GLES3 and GLES2 work normally. Just use a LG X Venture. I can see you disable Vulkan for some Andreno 4xx devices in 2018.3 but this one has 505 anyway so it won't affect it.

We have crash on two devices (Xiaomi Mi Mix 2s, Asus Zenfone 5z) when use Vulkan in our game. Unity 2018.3.8f1

cullen_unity · May 15, 2019

@Driven Did you ever find a fix for this, I'm having the same problem in 2019.1.2

Driven · May 15, 2019

@cullen_unity i didn't find a fix, the QA sent me a message that it is fixed in 2019.2+ ONLY which means every version below will have this error "forever", since no backport is planned as far as i know.

Dadlord · Jun 2, 2019

I don't think it was fixed. Whatever the version you'll try. I have tried 2019.3 alpha and still it have black screen on my Nokia 6. Doesn't happen with UE4 Vulkan builds.

ShilohGames · Jun 29, 2019

I ran into a black screen with Vulkan on Android. OpenGL ES3 works great, but Vulkan goes to a black screen. This was with Unity 2018.4.2f1 and a Samsung S10.

unity_W3rLGozcKkUuGg · Aug 5, 2019

I saw that Unity fixed that to >2019.1. I really hope that they can bring this fix to the 2018.4 LTS ASAP.

tiagoandr · Aug 12, 2019

No no, Unity didnt fix that. I just experienced the problem with Unity 2019.2.0f1! 2 days changing the setup of the whole S*** and I just found out after checking the logcat from Android Studio (and now with your comments)

Solution: remove vulkan from the player settings, keep only OpenGL ES3 or 2.
my device: xiaomi mi9

aleksandrk · Aug 13, 2019

@tiagoandr it would be nice if you could report a bug.

JesOb · Oct 9, 2019

Do we have bug report for this or I need to create additional one?
How to report bug about Unity internals that is visible only in builds?

aleksandrk · Oct 10, 2019

@Jes28 I don't think I've seen one. Please create a new bug report, QA will sort this out
When you create one, you can describe, what's happening and how to get to this state.

JesOb · Oct 10, 2019

I can not describe how to get to this satet I can link apk to bug report that is in this stet and only Unity Devs can know something.

And because of this I have ask how to correct create bug report. Will linked apk will help?

aleksandrk · Oct 10, 2019

It's preferable to have source code to debug this. So the best way would be to use the built-in bug reporter.

Hello, Aleksandr.
Ok, so I've submitted a bug report with minimal project, steps to reproduce included. It failed to render a Unity splash screen and an empty scene on Xiaomi Mi 9, but works as expected on Samsung Galaxy S8. Its just an empty scene with camera, URP + Vulkan, no source code at all
Bug id 1193349

aleksandrk · Oct 23, 2019

@Silentor666 great, thanks!
we'll take a look

Thanatos_Psychopomp · Oct 30, 2019

I just wanted to add that I am also facing this issue. OnePlus5 android 7.1.1 works perfect, OnePlus5 android 9 crashes while showing the unity logo. Galaxy S9 android 9 crashes while showing unity logo and Galaxy A6 android 9 works perfect.

JesOb · Nov 10, 2019

Any News?

Morgomir · Nov 13, 2019

Same problem here, working with Unity 2019.2.8f1 and both Tablet HUAWEI M5 lite10 and Fairphone 3.
Removing Vulkan from the player settings or moving it below GLES3 fixes it but also makes it way slower !
Especially when working with the device camera... framerate under 10/s

korzen303 · Nov 28, 2019

I confirm the problem with Xiaomi Mi9, Android 9 (MIUI Global 10.2.30) and latest Unity 2019.2.13f1. Empty project, empty scene -> black screen

JesOb · Nov 28, 2019

Unity answered that it is driver bug and it now in "Wont Fix" state

I have updated Drivers for Mi9 to latest November ones and now it works

korzen303 · Nov 29, 2019

OK, It worked after I have updated Mi 9 to MIUI 11.0.5.0. Tip: If you haven't received the IMUI 11 update yet change your Settings/Region to India and then trigger update by going to Settings/About Phone/System Update.
