I have *big* problems with intel drivers and qt4. Forms stay unpainted,
moving mouse over shows controls (eg QLineEdit, QComboBox etc), same app
works ok with nvidia or ati (qt-4.6.2).
I've finally found where's problem in my code, but I'm wondering what can
cause such problems.
When Qt::AA_ImmediateWidgetCreation is setted up, then have problems with
intel driver (others like nvidia, ati works ok), removing
Qt::AA_ImmediateWidgetCreation fixes problem.
Anyone ?
