OpenGL & Vulkan

When using GL_LINE_SMOOTH I get distorted lines, which at some moments can completely disappear. This appeared around after driver version 22.5.1. Below I have attached a video of the application on different driver versions and video cards. And also the source code of the application.

The correct work is shown on driver version 22.5.1 as well as on nvidia videocard.
