In light of this, I suggest re-considering whether a GLX Pixmap should be used by default for 6.3.0. Currently, a GLX Pixmap has to be specifically enabled by setting GRASS_GLX_PIXMAPS (whereas the trunk requires it to be specifically disabled by setting GRASS_NO_GLX_PIXMAPS). If it turns out that GLX Pixmaps work on a significant proportion of systems, they should probably be used by default, as they don't suffer from the inherent problems of trying to read a window's contents (clipping, occlusion, the window receiving events in the middle of rendering, etc). I say "a significant proportion" rather than "the majority", because the situation is likely to get better (rather than worse) over time. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
