[Bug 1753776] Re: Graphics corruption (or distortion?) in login animation to Xorg sessions

OK, this seems to be a Xorg bug in the "-background none" feature. Upstream bug reported here: https://bugs.freedesktop.org/show_bug.cgi?id=105518 Less likely but still possible is that mutter (used on the login screen) is corrupting the framebuffer and "Xorg -background none" is then innocently

Actually, the bug occurs with Unity 7 sessions too. That excludes mutter and gnome-shell. But I might have been too quick to eliminate xorg- server. ** Changed in: xorg-server (Ubuntu) Status: Invalid => Confirmed ** Changed in: gnome-shell (Ubuntu) Status: Confirmed => Invalid

[Bug 1753776] Re: Graphics corruption (or distortion?) in login animation to Xorg sessions

The pattern of corruption looks like a pixel format mixup or colour channel overflow. So I would bet it's related to the 10-bit/8-bit colour changes in Mesa and Mutter... I can't reproduce it on my desktop (Haswell, 10-bit monitor). I can reproduce it on two laptops (Kaby Lake, 8-bit panels). Is
