Check out http://discourse.mcneel.com/t/bugs-still-in-neon/511/6 for a workaround for the bump map issue you mentioned. This bug is filed already too.
I'll check on the viewport resizing crash but I haven't seen this yet here. If you have a sample file please send it to firstname.lastname@example.org with instructions of what to do to see the crash.
If you can try posting questions to the new forum on discourse that would be good since I think this forum will slowly see less traffic and eventually be replaced by the discourse one.
Thanks for all your feedback!
