OpenGlControlBase enters OnOpenGlInit with OpenGL errors

[Dragorn421]

Describe the bug

When implement OnOpenGlInit in an OpenGlControlBase and checking gl.GetError() for any error, there is one, presumably from something in Avalonia's code.

To Reproduce

Steps to reproduce the behavior:

1. Clone, build and run https://github.com/Dragorn421/DragoStuff/tree/ffe12b1003c3e6cd92419d7fdaab97b3c90c5dc4
2. Check the debug prints:

GL1.OnOpenGlInit
GL1.CheckError 1280
GL1.OnOpenGlRender
GL1.CheckError OK
GL1.CheckError OK
GL1.OnOpenGlRender
GL1.CheckError OK
GL1.CheckError OK

3. Notice GL1.CheckError 1280. It is printed by https://github.com/Dragorn421/DragoStuff/blob/ffe12b1003c3e6cd92419d7fdaab97b3c90c5dc4/MyOpenGLControl.cs#L29 , before the child control does any OpenGL call, so it seems to be an error originating from something in Avalonia.

Expected behavior

gl.GetError() should always return GL_NO_ERROR on entering child/user methods like OnOpenGlInit

Environment

• OS: Kubuntu 23.10 (Linux, X11)
• Avalonia-Version: 11.0.5

1280 is mean GL_INVALID_ENUM
Some operations use incorrect parameters, but this is related to the version of OpenGL

[Dragorn421]

Still in Avalonia 11.0.10

@Dragorn421 if you wanted to check newer version, worth to try 11.1 betas

Still in Avalonia 11.1.1
