Hi,
I have a problem with PlateButton not showing solid background as it
should. See screen shots from the wxPython Demo below. The gradient
background looks OK though. I’m running wxPython 2.9.4, Python 2.7.3
(32bit) on Win 7 64bit
Anybody knows what is going on? Any suggestions on how to fix it?

Looks like something has changed in 2.9 in regards to the window buffering and erase background behavior (again…).
Will need to make an update to the control but from some quick testing on windows the following fixes the issue:

Will need to test on other platforms before pushing update out.
You may be able to work around this in your code currently by creating a subclass of PlateButton, overriding OnErase to Skip() the event and specifying PB_STYLE_NOBG style flag when creating the buttons.
