[Mesa-users] R: R: another serious issue with OpenGL on Linux

[Gianluca Natale]

Thanks, actually I do not set multisampling.
Anyway, I do ask for a stencil buffer, maybe that causes the issue.

Hi Gianluca,

> I'll see what I can do. Maybe I'll have to switch from QGLWidget to QOpenGLWidget, as suggested in Qt5.

we're still using QGLWidget with Qt5.

You just have to ensure that the QGLFormat given to QGLContext doesn't request too much samples. We're reading the max number of samples from GL_MAX_SAMPLES_EXT and set it with QGLFormat::setSamples.

Greetings,
Daniel
