i've made a PR for this at: https://github.com/Subsurface-divelog/subsurface/pull/745
-------------------------------------------------------- Pull request long description: we have a bit of a problem with the map widget...it's QtQuick based and QtQuick2 needs OpenGL 2.1 on Desktop. it seems that some users are using prehistoric hardware or simply do not have good GPU drivers installed. without drivers installed Windows only has OpenGL 1.1. But this is a potential problem on all desktop platforms and we need to fall back to a software renderer. To my understanding Marble did the same. Changes made: notify the users in README that the desktop version needs OpenGL 2.1 at least. attempt to automatically detect older OpenGL and fallback to a software renderer. -------------------------------------------------------- please test. thanks lubomir -- _______________________________________________ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
