Hi, We are using Qt 5.5.1, D3D9 and ANGLE renderer. Rarely on some machines after resuming from Windows lock screen we see the following error logged "QWindowsEGLContext::swapBuffers: eglError: 12302, this: 0xf791378 ", that error keeps repeating and usually after some time the application crashes:

Any thoughts what can be done? We cannot use D3D11 which I suspect could fix this issue since we are seeing too many other random crashes and strange UI behaviour with it compared to D3D9.
