Vulkan UseTexture() and CreateResource() crashes

Target Platforms Mobile

It seems we are getting multiple crashes related to Vulkan.

Are these known errors? I have no idea what is causing them as it happens at different times, after playing for a while.

We don’t get any crashes on GL ES, but consistent crashes on Vulkan. We would really like to use Vulkan though for the performance benefits.

What Unity version?
If you are on the latest available 2020 or 2021 lts make a big report for the crash

3

2020.3.36. This is the only report we get (from the Unity Dashboard).

4

If it’s 1 user it might just be bad drivers or a random crash

5

I wish that were the case, but it happens from multiple people on different devices, and I really doubt it is bad drivers. Probably just a buggy unity implementation. It’s a pretty new flagship device. Snapdragon 865+

6

I can’t remember seeing a crash in UseTexture. You could try to disable GraphicsJobs.

Crashes in DataBuffer::CreateResource were fairly common but mainly in Editor and in general when running low on GPU memory.
Probably not exactly what you have.

Just wanted to follow up and say that did appear to fix the issue, thanks!

8

I meet the same crash 2020.3.40

9

If you can reproduce make a bug report

10

I might have the same crash with unclear error log in 2021.2 and 21.3. But graphics jobs don’t help. I simply switch from DX11 to Vulkan and my editor crashes at start 100% of the time in a large scene. Works in a tiny scene though.
It looks like Vulkan doubles my RAM and VRAM usage compared to DX11 so this might be the cause. I submitted a report but couldn’t attach my 100GB project.

11

I was told that this is the bug but the fix is only available in 2022.2 beta.

12

same issue at 2022.3.8f

13

How to deal with low GPU memory issue.
Any way to get the current usage and limit at runtime.
