I'm seeing sporadic flickering display at all times using OpenElec builds, both Isengard and Jarvis. It seems like a driver issue, the flicker starts with the openelec logo, before X has even loaded. It almost looks like the GPU is overheating. Is this a known issue?

I was using a build from 10/04 [1] before I saw the issue, but didn't upgrade until 10/26 [2], so the regression could be anywhere in that (very large) window. I'd be happy to try to bisect if archived builds are available. Reverting to the 10-04 build or the official OpenElec fixes the issue.

Hardware is an ASUS Celeron chromebox 2955U, connected via HDMI to a Denon AVR.

Is it the occasional horizontal line flashing across the screen? Because I am having that since updating to the custom EGL build of Open ELEC. I have the same Chromebox as you and a Denon 3311CI AVR connected via HDMI.
