Qt OpenGL applications doesn't work and crashes inside NVIDIA library

Qt OpenGL and QtQuick applications started when X screen isn't active on current VT doesn't work and sometimes crash inside NVIDIA library.

Other Qt non-OpenGL applications like gui/analogclock and gui/rasterwindow work and also other non-Qt OpenGL applications like glxgears and glxinfo does work even with inactive X screen (when current VT is console).

setting QSG_RENDER_LOOP=basic or QSG_RENDER_LOOP=windows doesn't make any difference.

To reproduce (need NVIDIA GPU with proprietary NVIDIA drivers):
1. Start X server
2. Switch to different VT
3. export DISPLAY=:0
4. start some Qt OpenGL application like examples/gui/openglwindow
5. Switch to X server VT

crash looks looks like

QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader
QOpenGLShaderProgram::attributeLocation( posAttr ): shader program is not linked
QOpenGLShaderProgram::attributeLocation( colAttr ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( matrix ): shader program is not linked
