As it happens, I just rebuilt the shiny demo from the 1.0.11 tarball on this ubuntu 10.04 system using compiz and with an nvidia graphics card, and it actaully works really well. Better than I've seen it work in a long time (and much better than it works on WinXP...) Maybe this is an artefact of the way compiz (and presumably other modern WM's) are compositing the display?

The same idea has occurred to me (and others I imagine.) It would be very cool if we could have a GL (or, say, GLES) backend, but I guess I haven't the skills (or time, for that matter!) _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
