I'm puzzled by this sentence:
"Apps seem to load but most controls are usable."
Do you perhaps mean "not usable"?
If so, can you be more clear: do the controls not appear? Do buttons appear but not work?
You indicate that reinstalling helps. Have you tried clearing the Safari cache?
We don't have any other reports of this. Before any fix can be made, we have to be able to reproduce the problem here.
