High memory consumption or memory leak on Intel integrated graphics #7704

Open EdiWang opened 1 year ago

EdiWang commented 1 year ago

Description

WPF application running on some Intel integrated graphics card is taking a lot more memory than it should. Even a pure empty WPF app takes 165.2 MB on startup.

3aedc63e2047a93783dd15d5ac35848

On other machine without Intel graphics, or disabling intel graphics card, or use software rendering, the memory consumption is normal.

There are two threads on Intel community site describing the same issue. But I am not sure if this is a WPF issue or Intel issue.

https://community.intel.com/t5/Graphics/Net-WPF-Application-high-memory-consumption/td-p/1434020 https://community.intel.com/t5/Graphics/UHD710-High-memory-usage-and-memory-leak-issues-with-WPF/m-p/1471504

Reproduction Steps

Expected behavior

Memory usage is around 10-30 MB

Actual behavior

Memory usage is around 150 MB

Regression?

No response

Known Workarounds

Set the WPF app to use software rendering.

public partial class App : Application
{
    protected override void OnStartup(StartupEventArgs e)
    {
        base.OnStartup(e);

        RenderOptions.ProcessRenderMode = RenderMode.SoftwareOnly;
    }
}

Impact

Users with some type of Intel graphics will have much more memory usage and potentially slow down their system.

Configuration

Memory consumption also has something to do with monitors:

It doesn't matter which screen the App is on, the more screens, the more memory usage.

EdiWang commented 1 year ago

@Anduin2017 You are using NVIDIA GPU, so you don't have this issue. It only happens to a few Intel CPU with integrated GPU.

Credhat commented 1 year ago

I am also confused about this issue. It is difficult to understand why a simple Net6.0 WPF application would result in such high memory consumption.

Here is some additional information. I hope this issue can be resolved. WPF Task Manager

Dxdiag Info

phreishauer commented 1 year ago

We have the same issue on a few recent Dell Laptops with 12th Gen Intel CPUs. In our case (32bit application) it leads to OutOfMemory and other exceptions in strange places.

qkevin commented 1 year ago

i can confirm this issue happens with my 12th Gen Intel CPU 12500 with integrated GPU 770, i created an empty wpf app, can confirm it consumes 100mb more memory in task manager. Snipaste_2023-07-18_14-01-56

allopatin commented 1 year ago

We are also encountering this issue. It's not only limited to what you described. In our case a static Image source is breaking the application completely in addition to exploding memory usage. The error we sometimes are able to catch is System.Runtime.InteropServices.COMException: 'UCEERR_RENDERTHREADFAILURE (Exception from HRESULT: 0x88980406)' which could suggest a driver issue. On a machine with 31.0.101.3251 Intel driver the implementation does not show this behaviour and works without issues.

We have escalated this issue through our hardware distributor to Intel and Microsoft. Sadly, it looks like none of them are ready do acknowledge the issue and instead try to blame the other party for it and hope to wait it out.

As it is only a problem on Intel GPUs with the Intel drivers enabled, i would suggest to contact Intel support if you are affected. Responding to the existing forum threads does not work as threads get ignored after a few weeks. Use a new thread or other channels and reference this issue. Maybe things start to move if enough report it.

pchaurasia14 commented 1 year ago

We are currently following with the DirectX team internally for this bug. It looks like there is an issue with D3D9On12 abstraction which is causing the spike in memory usage.

We will update you as soon as we know more.

DanielF95 commented 11 months ago

The problems are so obviously! - (and after 2 hours of research you can see that the problem comes at the time when microsoft changes the concept to the new wrapper D3D9On12). I can't understand why microsoft or/and intel ignores this bug. Many user have this problem since over one year !

Do you have news from this issue? We are currently struggeling with this problem and it is very urgent, that we get a solution! We will appreciate every kind of help.

PsychoDad9999 commented 11 months ago

Memory consumption of a Fullscreen WPF application on a 4K UHD Display + Intel GPU is insane. Using Software rendering fixes the issues, but we would prefer a better solution.

Our telemetrics currently shows a lot of OutOfMemory and RenderThreadFailure Exceptions and the majority of our target devices are using these gpus. Hope this will be fixed soon.

Onnotjee commented 11 months ago

Same issue here.

Software:

The workaround solution mentioned to use software rendering works indeed, but is not preferred.

We have the same problem Out of memory issues with our WPF based software. At both x32 and x64 builds, .NET 4.8.

CrazyWinner commented 10 months ago

Same thing on UHD630. It's a driver issue. Anything that uses GPU will leak memory no matter what(Tried with Qt and glfw). We have been having problems with Intel igpu's since 2021 and seems like Intel just doesn't care. What a trash company

The version of Intel® Graphics Driver is 31.0.101.5534 now. Could you retest this issues? @EdiWang

EdiWang commented 4 months ago

@lindexi I tested the latest driver, 31.0.101.5534 with the same hardware. This issue remains.

Xulunix commented 4 months ago

I can confirm that the issue remains on 31.0.101.5534 An empty unmodified WPF application still uses ~100Mb memory. An i noticed that window size affects consumed memory

lindexi commented 3 months ago

This could just be counting the GPU memory into memory usage.

lindexi commented 3 months ago

Sorry, I clicked the wrong button.

zerodev1200 commented 3 months ago

In the following environment, an empty WPF (.NET 8) application consumes approximately 650MB:

OS: Windows 11 Pro 23H2 CPU: Core Ultra 7 155H GPU: Intel Arc Graphics Memory: 32GB Display: 3840x2400 Intel Driver Version: Intel Arc Graphics 31.0.101.5007 Executing with RenderOptions.ProcessRenderMode = RenderMode.SoftwareOnly; reduces the consumption to about 41MB.

LiguangZhang commented 2 months ago

same issues on utra5 laptop using latest intel graphic driver.

lindexi commented 2 months ago

@LiguangZhang What is your intel graphic driver version? You can find the version of intel graphic driver in TaskManager.

任务管理器里面的 性能->GPU 里面可以看到 驱动程序版本

ali50m commented 2 months ago

same issue, Intel(R) Iris(R) Xe Graphics version: 31.0.101.4146

lindexi commented 2 months ago

Based on my analysis, this issue arises when using D3D9On12, as the memory that should be counted or stored in the GPU memory is instead accounted for in the WPF application. As indicated by the following stack traces, when wpfgfx_cor3.dll!CD3DDeviceManager::CreateNewDevice creates a device, the resources created are requested in the current WPF application by igdgmm64.dll. Since I am unable to fetch symbols from https://software.intel.com/sites/downloads/symbols, I am uncertain about which functions igdgmm64.dll has invoked.

Also on Ultra5 laptop with Intel(R) Arc(TM) Graphics(version：31.0.101.5449)

CainSakura commented 1 month ago

Same issue on desktop with Intel Arc A770 Limited Edition. Driver version 31.0.101.5590 and 32.0.101.5768

ShannonZ commented 1 month ago

The same issue with Intel HD 630 @ Windows 10 Ennterprise LTSC 2018. The wpf app was based on dotnet 6 and 8 .

ShannonZ commented 1 month ago

Here is a minimal reproduction project Minimizing the window would cause a sudden memory consumption with Intel HD630. The app has no business logic. But after being minimized, it consumes about 40GB memory.

ShannonZ commented 1 month ago

Nvidia Geforce GT 710 and ATI 6750 also have the same issue.

@ShannonZ Can you sure your process load d3d9on12.dll ?

ShannonZ commented 1 month ago

@ShannonZ Can you sure your process load d3d9on12.dll ?

Those old graphic cards (7th core CPU with UHD630, GT710) natively support D3D9. No D3D9On12 Wrapper.

lindexi commented 1 month ago

@ShannonZ Could you take the dump file and send the dump file to me or share it? I clone your repo but find nothing.

@ShannonZ Thank you.

I can sure your process do not load the D3D9On12.dll and the process take the 3GB memory

....... // ignore other more memory address

The above memory addresses take about 3GB memory. But I fail to know who alloc this memory.

I'd be even happier if you can use GFlags tool to help address the issues. I find the 0x0000023eb6a40000 address and so on is not the heap address, the GFlags may can not help...

And I can sure what you have is a different problem, and your issurs and this issues are different issues.

Guess:

The address above (0x0000023eb6a40000, 0x0000023eb8a40000, 0x0000023ebaa50000, and so on) takes about 31MB memory. And the 4K screen bitmap will take 3840*2160*4=33177600~31MB about 31MB memory.

I think the address above will be the bitmap memory and the memory of the address above is alloced by the video card driver.

Can I know what is your screen resolution?

@lindexi 1920*1080 This video demonstrates how to reproduce.

Some useful additional info:

  1. Comment the WindowChrome part out in Style could solve the leak problem. But I don't know why; (No minimization button, should press win+D to minimize the window) image;
  2. dotnet framework 4.5,4.7,4.8, dotnet6,8,9 have the same issue;
  3. Software rendering works as expected. And running the same exe on some other graphic cards has no memory leak.
  4. Driver versions from old 27.x to the latest 30.x were tested, no help.
  5. Restore the window to the normal state, those memory would be "released". Video
  6. Discrete Graphics Processing Unit like NVidia Geforce GT 710, ATI 6750 have the same issue. (This is why I think it's a bug of WPF, not graphic card manufacturers.).

The same issue with NVIDIA GeForce GTX 1650 and 3050 [2024/09/19]

I still haven't made any progress. Some friends have told me that the animation module may be causing the problem, but I haven't investigated it yet.

我依然没有什么进度。有群友说是动画模块导致的问题，但我还没空调查

@lindexi I think this is a quite serious memory issue. Can we raise the severity of this issue and ask Microsoft to put more resources?

@ali50m Thank you and I've already sent an internal email.
