[1.] One line summary of the problem:

Switching from an X VT to a Mir VT with Intel graphics causes heavy black flickering.



[2.] Full description of the problem/report:

This is a regression caused by https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c51f71679042a5f388d9580ffbede14c897f1e86. It still occurs with the current master head at https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e36f014edff70fc02b3d3d79cead1d58f289332e as of February 3, 2015.

As root, run the mir_demo_server from the Mir project located at https://code.launchpad.net/~mir-team/mir/development-branch on VT 1. Switch back to a VT running X, which is VT 7 on my Ubuntu machine. Switch back to VT 1. The Mir server will flicker heavily, both screen and pointer, which it did not do until the above merge commit.
