initial canvas painting of a form sometimes is messed up with custom form

The very first time some of my users go into a custom form the text (headings)  are a bit off.    If they get out and come in again everything is fine.   How can I prevent that initial bad canvas painting?

I'm using Oracle Forms Tools   version 6.0.8.28.0..   we are in Application 11 so that is the only version supported there.      This can happen to multiple users..  but only the first time they go into this form.   I haven't seen it with any other forms.
