Crash on RDP reconnect "Back buffer's device is not valid." in SetBackBuffer in GLWpfControlRenderer.Render

[SLMJanMatyssek]

Hi, I'm encountering a crash when reconnecting via RDP

Precondition

• OpenTK Version 4.9.4
• OpenTK.GLWpfControl 4.2.2 (newer is currently not possible due to the intel graphic problems)
• framework: .NET8
• Windows 11

Steps To Reproduce

1. Connect via RDP
2. Run Application - Rendering works fine
3. Close RDP connection
4. Connect via RDP
5. Error:

"ClassName": "System.ArgumentException",
"Message": "Back buffer's device is not valid.",
"Data": null,
"InnerException": {
"ClassName": "System.Runtime.InteropServices.COMException",
"Message": "0x88980803",
"Data": null,
"InnerException": null,
"HelpURL": null,
"StackTraceString": null,
"RemoteStackTraceString": null,
"RemoteStackIndex": 0,
"ExceptionMethod": null,
"HResult": -2003302397,
"Source": null,

},

Stacktrace:

• at System.Windows.Interop.D3DImage.SetBackBuffer(D3DResourceType backBufferType, IntPtr backBuffer, Boolean enableSoftwareFallback)
• at OpenTK.Wpf.GLWpfControlRenderer.Render(DrawingContext drawingContext)

is this a known issues? Are we doing something wrong? Can we do something to prevent this? Thanks a lot!

This issue is very likely related to the closing laptop lid issue in #30,. I don't know if there are any workarounds for it so far.
I've not had the time to look into updating the PR so that we can merge it, if you want to give it a go feel free.
