A short sleep() makes the splash screen display on those recalcitrant VMs:
if not pixmap.isNull():
splash = QtWidgets.QSplashScreen(pixmap,
WindowType.WindowStaysOnTopHint)
splash.show()
sleep(.05) # <-------- Allows the splash screen to show
splash.repaint()
I'll do some more testing with my various Linux VMs before putting in a new
PR.
Those small partially competed windows I mentioned earlier are not in fact
the splash screen trying to form. They are from some other temporary
window opening, incompletely painting, then closing or possibly getting
moved to their final position. With the sleep(), those windows show up
behind the splash screen. I'm not inclined to try to diagnose this
behavior.
