Yes, the crash happens during early startup of enlightenment, right after painting background and setting up cursor. > you are is the depth 16bpp BUT the visual is still 24bpp with 24bpp rgb > masks? xdpyinfo will tell you this. i.e. According to xdpyinfo, with driver prior to bisected commit root window is 24bit but with 2.21.6 it is 15bit. Also of interest, with 2.21.6 there are much fewer visuals listed: 15bit default, 15bit and 32bit while last working one show lots of 24bit visuals. Maybe the difference in number comes from the moment when xdpyinfo is called. For 2.21.6 right after starting Xorg, as only X client. For last good commit from xterm while running under enlightenment. See attached xpdyinfo outputs attached to the bug report. https://bugs.freedesktop.org/show_bug.cgi?id=63572 > more information needed. also consider using valgrind to catch the problem > earlier. A valgrind trace is not very informative.
