Created attachment 139886 [details] Qt Application renders correctly using MESA software rendering With intel integrated graphics, the Qt Surface example, that uses QOpenGLWidget, on Fedora 28 under an wayland session and then run under xwayland by starting the Qt application using the command: ./surface -platform xcb results in the Qt application being displayed correctly, but the 3D data visualization is shown incorrectly as blank panel (see attached). The same Qt application in a Wayland session with MESA software rendering also under xwayland as follows: LIBGL_ALWAYS_SOFTWARE=1 ./surface -platform xcb results in the application and 3D data visualization being displayed correctly (see attached). The same Qt application in a XOrg session results in the application and 3D data visualization being displayed correctly. The same Qt application in a Wayland session run under wayland results in the application and 3D data visualization being displayed correctly. This issue is logged as a Qt defect here: https://bugreports.qt.io/browse/QTBUG-68263 A similar issue is described for GNU Octave here: https://savannah.gnu.org/bugs/?51442
