I am getting this error:
Gdk-CRITICAL **: gdk_window_set_geometry_hints: assertion
GDK_IS_WINDOW (window)' failed python: ../../src/xcb_lock.c:77: _XGetXCBBuffer: Assertion ((int) ((xcb_req) - (dpy->request)) >= 0)’ failed.
when running my wxpython app on Ubuntu 8.04 running wxpython 2.8.8.1
(gtk2-unicode)
Googling for this error I found that this has been caused by making
opengl more threadsafe???
And that the problem is in the calling app??? Does this mean that this
is an wxWidgets issue?
Can someone shed some light on this?

I don't think this is necessarily (directly) gl related. I've had this
once in the past and it was just related to using threads. So in case
you use threads (or libraries which use threads under the surface such
as gstreamer, ...), be sure to package any gui code in a wx.CallAfter

Possibly. If you can make a small-as-possible sample that shows the

I will do when I can reproduce it reliably.

Do you do any GL calls from threads other than the UI thread?
they are not supposed to, actually I was not aware I was doing GL calls
at all.
