My application throws an OpenGL error after using sometime.

Hi, I have created an application where I render some images in my application. I render the images using vtk libraries. I am able to render the image and the application works perfectly fine. With continously working on the application like changing and rendering different images, all of a sudden after sometime the images does not render properly and it shows some glitches. But the application does not crash and I am also able to use the other options in the application except the image rendering which causes some glitches. When I checked the log message, I came across the following error.

CRT : ARB::createContext: wglCreateContextAttribsARB() failed (GL error code: 0x0) for format: QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize -1, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize -1, samples 0, swapBehavior QSurfaceFormat::DefaultSwapBehavior, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile  QSurfaceFormat::NoProfile), shared context: 0x20004 (The operation completed successfully.)

CRT : GDI::createContext: wglCreateContext failed. (Unknown error 0xc00705aa.)

WRN default: Unable to create a GL Context.

WRN default: QOpenGLWidget: Failed to create context

It is weird that this error occurs after sometime. Can someone please explain me, What went wrong?.

TIA.

Same issue here, are you using Qt 3D with Intel Integrated Graphics?
