    Description

      In a QGraphicsScene with a QGraphicsProxyWidget (with a non null QWidget as a proxy), if we call QGraphicsProxyWidget::resize() with a size >= QSize(24000, 24000) the application crashes with the following message in the output :

      createDIB: CreateDIBSection failed.

      You'll find in the attachment a simple project (.pro) that reproduces the crash : qtbug64120.zip

      Just compile and run, it will crash at the beginning
