PPB Grafx text ghosting
In PPB (Process Portal B) we have a Customer that has text on Graphics that Update. However there is Ghosting (Some of the text images are left when value Changes). If you Redraw the Graphic it clears until the next Text changes. Many years ago I recall the workaround was to use a Grafx function called Redraw but besides the Command which I tried we are looking for some detailed examples. We found other submodels
that have the Redraw call and tried the same but without success. Looking for a past Grafx PPB graphic person that recalls this issue and any examples using redraw to resolve it.
Thanks

Not sure if this will help, becasue my example is from an Advant OS500 graphic element.
An undelying graphic engine is the same - SLGMS - it may give you a useful clue...
text "ABC" -0.1 0.83
. dynprop (* (vis DataOk) \
(talign ValueAlign 3) \
(movex MoveValue) \
(color ValueColor) \
(stext ValueString "%s") \
(tfont ValueFont) \
(theight ValueFontHeight) \
(redraw))
