Lockup on start with Nvidia GTX 1070 #72

Open antoinecla opened 6 years ago

antoinecla commented 6 years ago

Step to reproduce:

Result: On start, application lockup with high CPU usage.

Attaching with debugger and breaking shows that the application is stuck in: GetGLProcAddressWGL.GetProcAddress(string function) Argument function is "wglGetGPUIDsAMD"

This was tested on a laptop with an Intel GPU and dedicated Nvidia GPU (GTX 1070). By default, the application uses the Intel GPU and runs without issues.

I note that WGL functions are accessed on EGL context disposition. This issue should change due commit for #71.

This issue should be repeatable if you're running WGL.
