A user reported a report crash for flatpak GnuCash in https://bugs.gnucash.org/show_bug.cgi?id=799301. After guiding him to extract a stack trace it was found to be a stack overflow bug in WebKitGtk’s GPU code. The usual workaround, setting WEBKIT_DISABLE_COMPOSITING_MODE=1 in the environment, fixed it. Regards, John Ralls
