[Qt-interest] Freezing OpenGL on Linux

[Jakub Zelenka]

Hi,

I have problem with freezing OpenGL widget after minimizing app window
or using QGLWidget in QTabWidget or QStackedLayout (after changing
current widget). It is only on Linux. I tested it on my notebook and
desktop and problem was always the same. It's in every app with
QGLWidget (including the Qt Demos). Can you help me? Thanks.

Jakub.
