Bug Vulkan crash editor with 2021.3.6f1

The editor crashes constantly when using the Vulkan API.

It crashes after 2 to 10 mins. After that it crashes immediately on startup if I reopen the editor.

Rebooting "helps" in that it gives me 2 to 10 mins again to use the Editor.

Running on Linux Debian Bullseye with AMD Ryzen 7 5800U.

The console is spammed with this warning before crashing:
Vulkan - Suboptimal memory type used for image because of low memory

Here's the error logs:

Vulkan - Suboptimal memory type used for image because of low memory
Vulkan - Suboptimal memory type used for image because of low memory
Vulkan - Out of memory when trying to allocate swapchain staging image

I haven't had a crash yet but the console is being spammed every single frame with warnings for "Vulkan - Suboptimal memory type used for image because of low memory", when I'm just in scene view in the editor. Just the console being spammed with 100 warnings a second makes doing anything pretty difficult.

I can't find any kind of reference or documentation on this warning, this page is literally the single result in google search (if enclosing the warning in quotes) at the time I write this.

From looking at the system performance monitor, I'm guessing it's because the scene has used up all 8gb VRAM on my 1070ti and is a couple of gb into shared memory (seems to use a bit more memory than DX11/12). A warning about that is fine, but having that warning shown every single frame is not (unless I am misunderstanding what the warning is about).

 

I had this issue. I figured out that I was making a bunch of new Texture2D's which are not destroyed automatically - you need to manually destroy them once they are no longer used or they will cause a memory leak. Figured this out by using Unity's Memory Profiler (https://docs.unity3d.com/Packages/com.unity.memoryprofiler@1.0/manual/index.html) (Profiler showed Texture2D size just kept getting bigger the longer the game was running). I know this was my particular situation but hope it helps someone.
