I want to draw OpenGL textures on Skia.

[qian-o]

Hello, I am currently encountering an issue where MSAA does not work after drawing on SkSurface when I bind a texture using SKImage.FromTexture. I am not clear on how to resolve this.

I have previously used the same code and extensions with MSAA working effectively when using the ImGui.Image function in ImGui.

The platform I am using is: GLES 3.2
MSAA extension: EXT_multisampled_render_to_texture.

The workflow is: I create a Mult sample framebuffer using the EXT_multisampled_render_to_texture extension, and the color attachment binds the texture that needs to be displayed.

This is the code for creating the frame buffer, where _glFormat, _glType, _glFormatAndType respectively represent GLEnum.Rgba, GLEnum.UnsignedByte, GLEnum.Rgba8.

Finally, bind to skimage using SKImage.FromTexture.

This is the project code address.

The problem has been resolved. Skia disables multisampling when rendering text, which causes MSAA to be unavailable during subsequent drawings.
