3458cc3 causes FE to hang during playback

Description
With the above commit applied, when watching a recording and pressing the Volume Down control on my keyboard the screen goes black and in about 2 seconds returns to the recording only it appers to be paused. Pressing P doesn't restart it.
Nor does pressing any other 'typical' MythTV key like Enter, i, Left Arrow etc.
I can use Ctrl-Alt-Left/Right/Up/Down? to navigate between my four screens. The programs running on the other 3 screens run OK and accept keyboard input fine.
mythfrontend must be killed and restarted to recover.
Also note that while watching a recording, the same symptoms can be duplicated by using Ctrl-Alt-<any arrow> to view another screen.
I'm running on Ubuntu 14.04 with lightdm FWIW. The Nvidia version is: 304.117.
The git bisect was done while the backend was running on v0.28-pre-1419-g62eaa39.
Git bisect results, gdb during the hang and FE logs are attached.

After all that, I started looking in Setup via the GUI.
"Vertical scaling" was set to 2 (which I've had for years.) I reset it to 0 and the symptoms went away. However, when I changed it back to 2, the symptoms didn't come back.
AlwaysOnTop? was set to 0 during the above. I'll keep trying to duplicate this, but for now it's OK to close. Sorry for the noise, but at least it's documented.
