I can see this, too, but only if XDBE is enabled. > In any case, the fix is trivial - just tweak the fluid file for the mandelbrot > UI to use a single window and all becomes well. > > Can others confirm that (a) they see this effect and that (b) the proposed fix > works as advertised and has no downside? Yep, works here. FLTK 1.1 uses "type Single" explicitly (svn log -r 5616), but FLTK 1.3 has been converted to "type Double" (svn log -r 6772). ISTR that we encountered this before, but somehow we must have missed the fix for this one. I propose to make it "type Single" again.
