Ubuntu splash screen not being drawn
I am using pyQt 4.7.3 on Windows 7 and PyQt 4.8.4 on Ubuntu.
The following code properly draws a splash screen on Windows::
@splash = QtGui.QSplashScreen(pm,
(qt.SplashScreen | qt.WindowStaysOnTopHint))
but does not (usually) draw the splash screen on Ubuntu. What happens is that a blank area appears, but nothing else. After the call to splash.show() the app creates and draws the main window successfully. That is, a significant amount of time can pass while the splash screen is blank.
The problem almost certainly is that the splash screen is not redrawn in time. Indeed, dropping into a debugger after splash.show() causes the splash screen to appear.
Alas, adding one or both of the following does not help::
# self qtApp is a QApplication object.@
Does anyone have any ideas what to do? Thanks.
Could you try with the same PyQt version on both platform ? That would allow to verify if it is a global problem of the PyQt version or an Ubuntu specific bug

This behavior has been constant for several PyQt versions on Ubuntu. It seems clearly to be a Ubuntu specific bug.
Then I would recommend contacting PyQt's developer to see if they are already aware of that problem
