@deakintsang

• Do you always get an error?
• Does it occur when the image file size is large? Doesn't it happen if it's small?
• If you are setting SoftEdge, can you set it to 0?

[buchizo]

I guess this exception from .NET Framework (WriteableBitmap) issue. https://stackoverflow.com/questions/8352787/how-to-free-the-memory-after-the-bitmapimage-is-no-longer-needed

Workaround

• Set SoftEdgeX and SoftEdgeY proerties to 0.

出现了多次了； 最大的图片，2M；可能是图片太大的问题，播放到此图片就会报错。

But I want to SoftEdge

But I want to SoftEdge

Yes, I'll fix it, but not yet.

Maybe this issue fixed by ver 3.1.11. (optimize load image process and remove leak of WriteableBitmap)

Maybe this issue fixed by ver 3.1.11. (optimize load image process and remove leak of WriteableBitmap) 3.1.11还是有问题

@deakintsang I doesn't occurred in my environment using 32MB png image (6k x 4k) file on Visual Studio 2019. Can you share your image to me?

打开两个项目，第二天，其中一个出错，另一个正常

图片是 jpg，2K 图片请见链接： https://github.com/deakintsang/vs_background

I try test long running Visual Studio using slideshow with your images.

• my environment: Windows 11 64bit / 32 GB memory / installed latest hotfix for .NET Framework and Visual Studio 2019
• ClaudiaIDE options: using slideshow, slideshow interval: 5sec, using softedge like as your config.

In my environment, I could not find memory leak and doesn't occurred this exception.

这几天正常，没有内存溢出报错。 但是有无响应

[buchizo]

但是有无响应

What's mean?

[deakintsang]

刚刚，VS上下滚动时出现此情况

[deakintsang]

但是有无响应

What's mean?

Visual Studio no response

[buchizo]

刚刚，VS上下滚动时出现此情况

Is the "User hardware graphics acceleration if available" option enabled?

Visual Studio no response

When it occurred? every time? Could you tell me your environment? (os ver/arch/memory, e.t.c.)

[deakintsang]

刚刚出错了

Could you disable this option (automatically adust visual experiance ___)?

[deakintsang]

禁用，还是出错

[buchizo]

• I removed MessageBox from exception
• However, I could not fix root cause.

[deakintsang]

I'm guessing that the BitmapSource doesn't take responsibility for freeing this object.

刚刚，VS上下滚动时出现此情况

我也出现了该问题，我猜测是代码编辑上方的下拉列表的问题，在禁用扩展后问题不再复现。在上下滚动时下拉列表会不断抽搐
