Comment # 14 on bug 104597 from Luke A. Guest

Looks like it's the same as
https://obsproject.com/forum/threads/xcomposite-colours-all-wrong.81265/ and
https://obsproject.com/forum/threads/xcomposite-window-capture-not-working.81389/.

It's been pointed out it's not Obs as TyMiles2012 moved back from the Oibaf PPA
on Ubuntu 17.10.1 back to standard drivers and it no longer affects him.
