[Qt-interest] MainWindow::paintEvent() constantly called

[Alexandre Courbot]

Hi,

You do not state
- How often paintEvent is called,
- What are the side effects on your application (blocked window?)

nor do you give some code that would allow us to understand where the
problem could come from. Please give more details about the issue!
