#16502 closed bug

FillPolygon to view which is child of BBitmap corruption — at Version 2

Description (last modified by smallstepforman)

I have 2 code paths to draw a BPolygon. The first one draws directly from BView::Draw() (via FillPolygon) and works fine . If I add the same BView to a BBitmap, then there is occassional corruption when drawing the BPolygon. See screenshots. The grey polygon is done directly via BView::Draw::FillPolygon. The coloured polygon is drawn when added to bitmap (it creates a mask used for compositing). Saving the BBitmap data also shows the corruption so it's not the compositing code path.

The black triangle below 6 is created when drawing via BBitmap::View::FillPolygon. It shouldn't be there (as evidenced when drawing directly to BView (grey screenshot)
