If/when you can find the time, please check the configure options and/or do tests with both XDBE enabled and disabled. In my tests I got different results with exactly the same Ubuntu setup (with gnome) running in a Windows virtualbox VM --- on two different Windows boxes (one with XP, one with Windows 7). > But; The 8.04 box is using XFCE for it's desktop, the 10.04 box is Gnome > with the stock ubuntu settings...

Yes, I guess that the WM could make a difference, and I know at least one STR where the WM obviously does: http://www.fltk.org/str.php?L2039 [but that's OT here]. It would be really good if you could rule out (or confirm) the WM's influence in this case by testing with and w/o XDBE (--enable-xdbe). Note that the FLTK 1.1 default is --disable-xdbe, whereas FLTK 1.3 is --enable-xdbe. > I know we have been "disadvantaged" in the past by the things that > compiz does on the display... Well, this is (was) due to some new behavior (new features) of the WM that FLTK didn't know about (setting X attributes to distinguish different types of windows). Thus I'd say that this is another class of change in the WM.
