    • Type: Bug
    • Status: Reported
    • Priority: P2: Important
    • Resolution: Unresolved
    • Affects Version/s: 5.6, 5.7
    • Fix Version/s: None
    • Component/s: GUI: OpenGL
    • Labels:
      None
    • Environment:
      Arch Linux with latest NVIDIA beta drivers 361.16 (nvidia-libgl-beta) (can be reproduced with 358.16 too)
      also libxcb compiled from git master

      GPU NVIDIA GeForce GTX 650 Ti

      Description

      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
      Problem creating accessible interface for: OpenGLWindow(0x7ffdf7b796e0)
      Make sure to deploy Qt with accessibility plugins.
      openglwindow terminated by signal SIGSEGV (Address boundary error)
