JP,

I just finished testing this and yes build wxWidgets against GTK3 seems
to have some very serious issues. I may try disabling the graphics
context to see if thing get any better but the drawing and some of the
control window rendering is broken. I wonder if we are first to
discover this? I will also try building the latest wxWidgets source
from the repo to see if any of the issues have been resolved. Thanks
for figuring this out. We will definitely have to let users know so
they can make the appropriate build decisions.
