Opengl glsl problem

[nettory]

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);
}
