Yes. But I haven't begun to find out what's going on.
I've seen the same effect in simple static-text-dialog-item after 
just loading a file (rather than running a saved image). I wondered 
if somehow the layer ordering has messed up.  They seem to be there, 
know about their view-container, wptr, dimensions etc. and respond to 
clicks OK, just be invisible.

I have no idea yet.
Current thinking is that some erase operation elsewhere has moved out 
of its bounds, so drawn over the dialog.

I find various small offsets have crept into various parts of dialog 
drawing under 5.2.
I plan to systematically replace area erase and fill operations with 
solid color, in hope of seeing where any area change has crept in.
