I just noted that my version of Qt5 doesn't support QOpenGLWidget and I read in another report (I can't remember which) that this "black background" had been observed by others (including Markus I think) up to the point where jwe introduced the use of QOpenGLWidget instead of QGLWidget.

I'll assume that that my version of QT5 is outdated and close this report.

This may also be due to a bug in my version of Qt (5.2) which has been fixed in later versions. If it is the case then we can probably close this report since mint 17.3 is based on ubuntu 14.04 which will probably not be supported anymore at the time we release Octave 4.4

Isn't this just a deficiency in the nouveau driver for 17.3?

I'm running Linux Mint 18.1, with intel graphics card and nouveau driver and the example works for me.

The title says it all:

I am using nouveau driver with an intel integrated graphics card on linux mint 17.3

I can get rid of this behavior using the following hack:
