'Avalonia.OpenGL.OpenGlException': Unable to make the context current #5562

afcsoft · 2021-02-25T21:42:05Z

Describe the bug

OpenGL rendering controls works just fine but about in 2 minutes, it crashes with this exception:

'Avalonia.OpenGL.OpenGlException': Unable to make the context current

Also, nobody returns my e-mail about paid support request. Hope you guys are okay.

To Reproduce

Open XamlControlGallery project
Run it
Just wait for crash.

Disabling AllowEglInitialization helped a bit. Not crashing about 5 mins. Still same exception.

I am getting the very same issue if WGL is enabled even for simpler apps on various Windows 10 and Windows 11 machines.

You can see that in TID the thread id is 7, hence, not the UI thread which would be 1.

Maybe this helps...

Hanprogramer · 2022-03-09T14:15:25Z

Still happening. But randomly. I'm not sure what's causing it

jmb10101 · 2022-05-22T22:23:49Z

Is there any update on this issue or plan on working on it? It is still happening. This should be a very high priority bug as it is essentially a non-starter for any project that wants to use OpenGL within Avalonia on Windows.

kekekeks · 2022-05-23T09:56:03Z

There are plans to finish and merge #6391 before 11.0. That should be way more stable.

StipecMV · 2022-10-24T10:56:55Z

That is strange, I got the same exception on X11

kekekeks · 2022-10-25T06:14:04Z

@StipecMV that's a completely different issue. Your glXGetProcAddress has failed for glXCreateContextAttribsARB. Which Linux distro are you using?

afcsoft · 2022-10-25T13:20:02Z

Any updates?

Hanprogramer · 2023-01-06T07:52:40Z

Still happening, please fix this issue, as this is very disturbing. The issue happens only on NVidia graphics cards. I know this because I was writing my on UI Framework and having the same issue. The best way to handle this is just to add Try/Catch when drawing and handle specifically OpenGlException, then just print the exception instead

"The issue happens only on Nvidia graphics cards" is incorrect. Intel/AMD/Nvidia does not matter. It throws this exception randomly. It is just an OpenGL implementation error.

What caused the error then? I'm curious. Is it about threading?
Edit: if i changed my application settings from the NVidia control panel to "High performance NVidia graphics" which uses the dedicated GPU instead of integrated (by default). The error goes away

Edit2: yeah i forgot i did send a screenshot before from my AMD machine. But still edit1 is something we should think about

afcsoft · 2023-01-06T08:02:34Z

It is just an OpenGL implementation error. And your last statement contradicts with your first statement. Which one is true?

Hanprogramer · 2023-01-06T08:05:41Z

I thought it might be from threading. But i checked again without threading turned on on my own UI framework, still the same. Turning on "high performance" mode on nvidia still solves the issue, but we can't expect end users to do this.

afcsoft · 2023-01-06T08:09:47Z

I don't think windows or any driver will change to active gpu during the runtime. So that may be true that integrated gpus do have a problem with avalonia's opengl control. But my tests shows the almost opposite. This exception occurs very randomly. That does not mean it won't happen. It is likely to happen anyone that uses avalonia's opengl control in an app. This error will never get a solution from avalonia team, (This is just my guess) It is possible that they can't replicate the issue at all.

Not just Avalonia though, my own UI library also have the same problem. It uses Silk.NET OpenGL for backend and SkiaSharp. Could either be problem with OpenGl and .NET itself. But this is just my guess

EDIT: Using the dedicated graphics device no longer fix my problem. Idk why

EDIT2: Here's how i fixed it on my own ui library:

                try
                {
                    SkiaCtx.Flush();
                }
                catch (Exception e)
                {
                    Console.WriteLine(e);
                }

Should be fixed with #9639
Also, UseWGL is not required and not recommended after #9925
