"There are gl errors: invalid operation" about meshlab HOT 4 CLOSED

The issue is well known. They are all (or, at least, the one we know...) derived from the Qt framework implementation on Mac OSX. Unfortunately, even if we tried really hard, it seems to be impossible to remove them.

i am impressed at the ease that you just close severe bugs like those...

Maybe if you show me the log I might be able to help.. What's the use of "updated" Meshlab if it cannot handle basic GL operations? Which version of Qt are you using? Are you using Qt's 5.1 interpretations of OpenGL or are you using ARB_extensions which are infamous for not working well with Qt? More info please

Sorry for the lack of explanations.
It is an issue that is not really critical (they are warning) and quite hard and complex to be solved.
So it is not on the top of the priorities.

To be more precise it is due to our, deprecated use of QGLWidget instead of QOpenGLWidget.
As was discussed here:
http://stackoverflow.com/questions/33545006/qt5-attempt-to-set-a-screen-on-a-child-window-many-runtime-warning-messages
this is probably a bug in Qt that will not be fixed...

fair enough @cignoni
