Intel UHD Graphics Driver problem (OpenGL)

[attix]

Intel® Arc™ & Iris® Xe Graphics - Windows driver  (ID 785597)

Environment: Intel Core i7-13700K or i7-12700K

OS: Windows 10 or 11

Known good drivers: 31.0.101.4338, 4335 beta, 1371

Known bad drivers: 31.0.101.4669, 4575, 4369

The CAD application I develop (for 15+ years) is using OpenGL 2.0 graphics.

The item selection / pick became unreliable with the new drivers while still good with the old ones (also good with the amd/nvidia discrete graphics drivers)

The problem is with the selection feedback mechanism of OpenGL 1.x.

Also there is an other problem (what I have a workaround for but I think a serious problem):
In GL_SELECT render mode the empty glBegin/glEnd pairs (without vertexes sent out between them) cause the application crash by the graphics driver. Here is the code to reproduce this 2nd problem in OpenGL 1.x:

glRenderMode(GL_SELECT);

glBegin(GL_LINES);

//no glVertex3f(...) calls here

glEnd();
