GLWidget render issue in release mode

[LudoJ]

Hi,

I have some issues with Open GL on a computer. So I've tried compiling the hello GL example from: http://qt-project.org/doc/qt-5/qtopengl-hellogl-example.html

Everything is fine when I compile in debug. But when set to release, the GL Widget does not get painted.

I use QT 5.3

Any idea ?

Hi and welcome to devnet,

You should also add the OS you are running

Of course sorry...

Windows Seven 32 bits

Which package did you install ? Also, if you're on 5.3.0, you should try 5.3.1

Just moved from 5.3.0 to 5.3.1 and I still have the same issue.

The PC I try to run it to is a small eeePC. May be the graphic card does not have the latest OpenGL ? Is there a way to tell QGLwidget to use an older version ?

BTW, the same project works fine on another platform...

It should not make any difference between debug and release… QGLFormat comes to mind for selecting which OpenGL version you want to use

Been playing around with this and I've managed to make it work simply by decreasing the openGL version. So I guess that the graphic card driver is kind of cheatty on that computer...

Thanks anyway... :-)

Update !

More seriously, it's pretty strange that it's working in debug and not in release… Anyway, glad you found a solution in between.
