[Intel-gfx] Video glitches E3845 ATOM, Fedora 21

[Rogers, Martin]

All,
I'm seeing weird video glitches on the Intel BayLey Bay -i CRB board, with Fedora 21, XFCE, and
I hope someone can help.

This board has a dual-core ATOM SOC similar to E3845.

Reproduced on Fedora 3.17.4 and 4.1.13 kernels.
And, just reproduced it on Intel's 4.3.0 kernel (https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.xz) also...

To recreate, open an xfce4-term.  Generate some output until the cursor is at the bottom (so the next
command will cause scrolling).  Wait 5-10 minutes.  Type "ls" (or echo, or most anything; even ssh'ing
into the board and doing a "wall hello", so that the terminal scrolls, can do it).

An area of the screen, usually near the top, will be either a solid, text-colored, rectangle, or a "garbled"
area resembling "warped" or torn text at an odd angle.
Pic attached.

Hitting Enter or otherwise scrolling again will redraw the window properly; however, moving another
terminal window over the anomaly and back will NOT cause the glitchy window to be properly redrawn.
