Practically nothing. 

RHIDE uses TVision library to work with screen. It is not doing it 
directly. I also didn't have experienced such problems.
So I suggest downloading v2tk/tv1010s.zip and testing whether You 
can reproduce problem with TVision examples (and running them 
under debugger to see what is screwing screen up)
