Description Daniel Stone 2017-05-26 13:47:29 UTC 
Whenever I take a screenshot using the Wayland backend, the R/B channels are swapped. Maybe GL's big-endian (sorta) pixel format descriptions vs. DRM's little-endian format descriptions confusion? i.e. DRM_FORMAT_XRGB8888 == GL_BGRA_EXT.

Do you have https://git.gnome.org/browse/mutter/commit/?id=374bb630f044d430206bd5e6f3bd2f670fcf51fb (it's included in 3.25.2) ?
Comment 2 Daniel Stone 2017-06-13 10:05:43 UTC 
Ah no, sorry, the version was wrong. This is with 3.24.2 in F26; I'll try with 3.25.x whenever it lands there I guess.
Comment 3 Rui Matos 2017-06-13 12:24:16 UTC 
Ok, marking as a dupe of bug 779234. I updated the f26 package to include that fix so it should appear there in a couple of days. Re-open if it's still not fixed then.
