[BUG] Hard crash on Linux ARM64 on 3.119.0

[Swordancer]

Description

We upgraded our application from .NET 6 to .NET 9. Some external dependencies use SkiaSharp version 3.119.0. The application crashes, but only on Linux ARM64. It works correctly on Windows. I tested this on our device with an IMX8 processor and on a Raspberry Pi 5. In both cases, the application closes and does not leave any trace in the logs. It worked on 2.88.8 and .Net 6. I already tested preview version of 3.119.1 and the same thing happens.

I have prepared a test application to reproduce this issue. For testing, you need, for example, an RP5, and it is enough to build the project in VS2022 for .NET 9 with the Blazor workload. After launching, simply go to localhost:8841 in the browser and press the button. The code is in the Home.razor file.

I know the crash is caused by SkiaSharp, but I have no idea why, so I am unable to help further in this matter. I have no clue if .Net 9 is to blame or rather SkiaSharp itself.

Use publish profile to publish app on ARM64.

Triage Summary

Labels will be applied to highlight reliability issues on Linux ARM64 with SkiaSharp, as well as specific graphics backends involved in the rendering process.

This issue is not explicitly mentioned as a regression, but it reflects critical behavior that may affect usability.

Additional remarks:

• The issue points to significant reliability concerns due to hard crashes on Linux ARM64.
• SkiaSharp is identified as the root cause of the crashes, particularly in the context of rendering graphics.

Detailed Summary and Actions

Summary of the triage:

• The issue describes a hard crash occurring on Linux ARM64 while using SkiaSharp version 3.119.0.
• Core components involved are OpenGL and Vulkan, both of which are used for rendering graphics on the affected platform.
• The issue specifically pertains to SkiaSharp.Views.Maui, indicating that the crash is likely related to the functionality of views in the library.
• The crash's occurrence is tied directly to the Linux operating system on ARM64 architecture.

Summary of the actions that will be performed:

Action	Item	Description
Apply Label	tenet/reliability	The issue describes a hard crash on Linux ARM64 with SkiaSharp, indicating reliability concerns.
Apply Label	backend/OpenGL	The issue relates to rendering using SkiaSharp, which involves OpenGL for graphics operations.
Apply Label	backend/Vulkan	The situation pertains to graphics rendering on ARM64 devices, thus relevant for Vulkan usage.
Apply Label	area/SkiaSharp.Views.Maui	The issue pertains to a hard crash specifically related to views functionality within SkiaSharp.
Apply Label	os/Linux	The issue describes a crash that occurs directly on Linux ARM64 systems.

This entire triage process was automated by AI and mistakes may have been made. Please let us know so we can continue to improve.
