[Bug 104540] Corrupted colors in OBS-Studio window capture

https://bugs.freedesktop.org/show_bug.cgi?id=104540

--- Comment #2 from Mario Kleiner mario.kleiner@tuebingen.mpg.de --- Just to add a bit to this: Testing this also on Kubuntu 16.04.3 LTS in X default color depth 24 bit and running apitrace on obs showed nothing suspicious to me wrt. selection of fbconfigs and visuals, creation of framebuffers etc. Just regular 8 bpc fbconfigs. The color corruption did happen with the x-composite input plugin, but not with the xshm input plugin.

So the corruption seems to stem from the x-composite based grabbing/input side, not from the output/rendering/display side.
