- My application displays several GL windows that are controlled by popup
- menus (and sub-menus of varying size). The popup menus are displayed in
- the PUDRAW or OVERDRAW bit-planes using noborder(), winopen() and
- prefposition(opx, opx + sizex, opy, opy + sizey). Sub-menus are displayed
- using winposition(). In 3.X I ignored the redraws caused by popup menus and
- everything was fine (I ignore the REDRAWs because each window takes about 5
- sec. to display). In 4.0.1 when I go to sub-menus I get random colors where
- the original menu/window was located.
-
- Is there a way to clear the NORMALDRAW bit-planes so I can see through them,
- or can I open a window that only has PUPDRAW bit-planes? It seems that
- someone would have run into this problem, is this a mixed GL, X application?
