Okay, thanks to all who took the time to reply.
What a shame; I hadn't planned on spending Easter weekend learning to do kernel upgrades, but . . . here it goes.

Well, it could be the same, but the bug report does seem to refer to the bug being in kernel series 3.18. I am just using whatever 3.10 series kernel comes standard with Centos 7.x.
Well, the CentOS kernel is a 3.10 kernel in name (or number) only. Red Hat backport much stuff from later kernels, and in this case that includes much broken code for the Intel i915 driver. The code is broken from around 3.15 and still not completely fixed in the current 4.0-rc6 code base. Updating to a newer kernel, and hence a newer i915 driver, may or may not help, but it doesn't hurt to try.
I don't know anything about bug reports, and I an not familiar with swapping out kernels in Centos.
BTW, is El Repo another name for the EPEL repository?
No, they are two completely separate repositories:

Hello!
No updates for days until 2015-04-01. Then presented with huge
steaming
pile of updates all at once, apparently related to Centos 7.1 release.
After reboot, there is a problem with the video. It seems to flicker
when
the mouse pointer touches the screen edges. Also, sometimes when
viewing
pages in Firefox, the window becomes partially covered with horizontal black lines.
During reboots, before the login screen appears, there are quickly disappearing messages seeming to include references to "drm:9" and some sort of "underrun".
In the terminal window, I get a message:
ABRT has detected 3 problem(s). For more info run: abrt-cli list
--since
1428078184
When I do that, I get:
id (blah, blah) reason: WARNING: at drivers/gpu/drm/i915/intel_display.c:869 intel_wait_for_vblank+0x211/0x220 [i915]() time: Fri 03 Apr 2015 11:41:49 AM CDT cmdline: BOOT_IMAGE=/vmlinuz-3.10.0-229.1.2.el7.x86_64 root=UUID=(blah, blah) ro vconsole.keymap=us vconsole.font=latarcyrheb-sun16 rhgb quiet LANG=en_US.UTF-8 count: 1 Directory: /var/tmp/abrt/oops-2015-04-03-11:41:49-590-0
Does this kernel.org bug look similar to yours?
https://bugzilla.kernel.org/show_bug.cgi?id=86771
I suggest you try kernel-ml from ELRepo and see if that fixes the issue.
