Hi, The below diff brings two fixes, and are exclusive to powerpc, with no impact on other archs.
> Fix javascript runtime It appears that a Void-PPC developer managed to fix JavascriptCore crashes [1]. There are a lot of 'ifs' and 'buts' in the bug report but it fixes that problem nonetheless. That's why i'm keeping it only on powerpc, and as-is so it can be synced with their patch. > Fix colors Then i had these funny colors [2]. It appears that disabling context GL (only on powerpc) helps. While building, i had to do a second patch to fix a missing header. I've reduced the size of the haystack about this issue, but i may not be able to fix the code myself, which is sad since it impacts performances. Yet this provides a better user experience indeed. With that fixed, i'm now able to browse as seen on amd64 with my PowerBook using midori [3] and surf. To potential testers, note that media playback may not work due to missing gstreamer plugins either because they're not marked as depends, or some of them requiring pulseaudio -- that means rust. If you have freezes or panics with a radeon video card you'll need a kernel with that commit in [4]. Comments/feedback are welcome, Charlène.
