Thank you for the additional information. I did some more testing for some of the specifics that you mentioned, but unfortunately did not see anything unusual happening. It all seemed to work normally for me. If it is something that only happens occasionally, I may have just gotten lucky and avoided it when I was looking around.
We have a fix internally for the text size issue. I am going to try to get a hold of that fix and run some more tests with it to see if it corrects everything I have seen so far. If the issue that you are seeing with buttons and text fields is actually related, then this will probably fix that for you as well.
