Hi! I'm not sure, but I've been struggling with this bug:
media-libs/mesa-13.0.0_rc2: libGL crashes on hardened AMD64 https://bugs.gentoo.org/show_bug.cgi?id=598593 ( my duplicate is at: =www-client/firefox-49.0 segfaults with >=media-libs/mesa-13.0.0_rc1 on >=4.4.8-hardened-r1 https://bugs.gentoo.org/show_bug.cgi?id=598700 ) and it looks like (I had better show you the standard output when starting firefox 49.0 on plain 4.8.3 kernel: ATTENTION: default value of option force_s3tc_enable overridden by environment. GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications. 1478449652215 addons.productaddons WARN Failed downloading XML, status: 0, reason: error (firefox:5208): GLib-GIO-CRITICAL **: g_loadable_icon_load: assertion 'G_IS_LOADABLE_ICON (icon)' failed and a few more lines to that effect. After some ducking for info I see that: https://en.wikipedia.org/wiki/S3_Texture_Compression is mostly used for games (and I'm not a gamer.) But it looks like, apart from mesa alleged fix (see in the bug report) not having propagated to us, [it looks like] that s3tc functionality is missing for my Firefox to behave... There have been various tips in the various distro flavors about enabling s3tc, but I couldn't get it to work in Gentoo. Such as after emerging: # emerge media-libs/libtxc_dxtn and issuing: $ force_s3tc_enable=true firefox That still got me the line: ATTENTION: default value of option force_s3tc_enable overridden by environment. Also, the useflag: https://packages.gentoo.org/useflags/s3tc only has: app-emulation/wine as sole customer at this time... I wasn't sure this was a post for the bug report that I linked to above, so I'm asking here on the users list. Anyone has any more clue about this issue?
