Without seeing a line of code, that's a bit hard to guess... but:

1) Have you checked that the EVT_NOTEBOOK_PAGE_CHANGING event handler
is called only *once* when you switch a page?
2) Does this behavior exist if you use other notebooks (i.e.
FlatNotebook, wx.aui.AuiNotebook)?
3) Are you using event.GetSelection()/event.GetOldSelection() in your
EVT_NOTEBOOK_PAGE_CHANGING event handler? If yes, in which way?

This looks like a sizer problem... are you using a sizer to hold your
OGL canvas inside the panel? If the answer is no, you should. If the
answer is yes, you should probably try to reproduce the problem in a
small and runnable app you can post here. BTW, if you are using a
sizer, have you tried calling Layout() when you switch the notebook
page (even if this should *not* be required)?
