Opengl glsl problem

Hello. I have a problem using the gl_SampleID variable in a shader on an Intel Iris XE Graphics on opengl app.

Application hangs, in some cases with windows. There are no problems on the video card of another manufacturer

 

Driver version 31.0.101.3413.

OS Windows 11 Home Single Language build 22621.521

small example:

void main()
{
int num= gl_SampleID;

if(num==0)
FragColor=curvatureResult();
else if(num==1)
FragColor=vec4(0.5,0,0,1);
else if(num==2)
FragColor=vec4(0,0.5,0,1);
else if(num==3)
FragColor=vec4(0,0,0.1,1);

else
FragColor=vec4(0,0,0,1);
}

Hello nettory,  


  

Thank you for posting on the Intel® communities. I am sorry to know that you are having issues with the Intel® Iris® Xe Graphics.


  

In order to better assist you, please provide the following:  


1. Did you develop the app that you are using?

2. Are you getting an error? If so, can you take a picture?

3. Does this issue happens on the non-insider version of Windows?

4. Are you using a laptop or desktop computer?

5. What is the brand and model name of your laptop or motherboard (if is a desktop computer)?

1. I am one of the app developers.

2. No error messages unfortunately.

3. Yes, I used the non-insider version of Windows.

4. I tested both on a laptop and on a desktop computer.
