Difficulties with launching OpenGL samples with latest changes to InteropWindow infrastructure #116

Closed shajder closed 2 weeks ago

shajder commented 2 weeks ago

@Beanavil I wasn't able to launch OpenGL samples (neither nbody nor conway) with the latest updates. The error message is:

OpenCL Utils error: Selected device isn't interoperable with the current OpenGL context.

I've tried with nvidia and intel platform with the same outcome. It looks like creating OpenCL context fails. My OS is Ubuntu 22.04

Additional remark: I verified similar interop GL samples from @bashbaug repo and it works just fine so I am assuming something may be wrong with recent corrections to InteropWindow infrastructure.

FWIW, this works fine on my Ubuntu 22.04 system. I do see this output:

Warning: The created OpenGL context does not fully meet the settings that were requested
Requested: version = 3.3 ; depth bits = 32 ; stencil bits = 0 ; AA level = 0 ; core = true ; debug = false ; sRGB = false
Created: version = 3.3 ; depth bits = 24 ; stencil bits = 0 ; AA level = 0 ; core = true ; debug = false ; sRGB = false

But the interop context and buffers are created just fine.

Yes, I just confirmed on other machine GL samples works. This is clearly problem with Ubuntu configuration - X11 chooses intel which is not prime platform for my display. Thus, closing the issue!
