with glWindowSettings.setGLVersion(4,1); the example-demo works ok on Mac 10.11.2/AMD Radeon HD 6750M

[o2co2]

@jvcleave Thank you! My computer is a macbook pro windows nvidia geforce gt 750m. Is there a solution to the problem?

[jvcleave]

I can't replicate it. Does the example-demo work with 4,1 for you?

[o2co2]

@jvcleave Not run. @Geistyp As shown error

@jvcleave You can help me? My computer is a macbook pro windows8.1 nvidia geforce gt 750m. glWindowSettings.setGLVersion(4,1); Not run. glWindowSettings.setGLVersion(2,1); ok run.

[jvcleave]

@o2co2 I don't think I can

[o2co2]

@jvcleave g.IO.RenderDrawListsFn(&data); Here throws an error.

[o2co2]

As shown error

[o2co2]

void EngineGLFW::programmableRendererDrawLists(ImDrawData * draw_data)

glDrawElements(GL_TRIANGLES, (GLsizei)pcmd->ElemCount, GL_UNSIGNED_INT, idx_buffer_offset);

Here breakpoint occurs.I do not know what is the reason?

@jvcleave https://github.com/ocornut/imgui/issues/350 http://stackoverflow.com/questions/15041120/crash-at-draw-call-in-nvoglv32-dll-on-new-video-card

[prisonerjohn]

Was this ever resolved? I'm getting a similar exception on Windows with the programmable renderer.

[jvcleave]

@prisonerjohn still unresolved - I really don't know what is going on as I don't have a Win Machine accessible to test on

[prisonerjohn]

The exception is definitely happening on the glDrawElements line, but I can't really figure out why. I checked the element counts uploaded vs drawn and it doesn't look like there's a buffer overrun. I have a feeling it's probably something similar to https://github.com/ocornut/imgui/pull/322

I wonder if converting all these GL objects to an ofVbo would solve it... Is there a reason why you didn't go that route? Otherwise I might try it out.

[jvcleave]

I tried it but the color conversation is slower and glScissor doesn't work.

[jvcleave]

If you guys want to try the old version that uses ofVboMesh - that is here

https://github.com/jvcleave/ofxImGui/releases/tag/OF_090_RC

[prisonerjohn]

Ok that one is running... at 3fps

[jvcleave]

Ha - it wasn't that bad before on a Mac https://vimeo.com/137275102

[jvcleave]

@prisonerjohn is the example-demo showing this exception for you? I am using Win10/OF 9.2 and VS2015 and not seeing anything.

Edit: I am using an AMD Radeon HD 6800

[prisonerjohn]

I think so, but only on the programmable pipeline... And I'm on NVIDIA (GTX 760 I think). I'm about to boot into my Windows machine and will try again in a little bit.

[prisonerjohn]

Confirming that example-demo is throwing the exception for me. I don't have a non-NVIDIA setup to test on unfortunately.

[o2co2]

@jvcleave @procedural This error occurs only on NVIDIA GTX 750 760 series, On osx win will error. very strange.

I can not solve.

[multiburst]

Same here on Linux, hardware is a NVIDIA 580...crash occours as soon as opengl version is set to 3.

[jvcleave]

@multiburst are you able to use emptyExample with Linux/Nvidia? Mine crashes right away

Edit: emptyExample with the Programmable Renderer that is....

[multiburst]

@jvcleave Example doesn't work as well, same error. Only the version utilizing ofVboMesh runs, with an acceptable performance.

Drivers are legacy nvidia-340xx.... OF 0.9.2

[o2co2]

@jvcleave @prisonerjohn @multiburst @hluisi https://github.com/xnamahx/ofxImGui/tree/gl3.1 Run the program. No errors, thanks! @xnamahx

[prisonerjohn]

Cool, that branch is working for me too.

[wasawi]

Same here. That branch is working with an Nvidia card. Will this be merged somewhere in this repo?

[jvcleave]

Master now has a similar patch and should be working

[wasawi]

Thanks! yes its working.

[jvcleave]

Great - closing then :) thanks for porting @prisonerjohn
