I forgot to mention, the bug only occurs after suspending the system and waking it up again. In that case, moving the mouse pointer around on the build in laptop screen triggers the flickering, while the external monitor works just fine.
My Lenovo X201s shows the same symptoms with v4.1.0-rc1, and your patch seems to help.
Another detail: The flickering only happens when both outputs are active, using xrandr to disable one output makes the other one working fine, again.
Might be unrelated, but I only managed to trigger the bug when the system is suspended after the synergy server has started.
I don't have synergy installed, so this can't be a strict requirement for triggering the bug.
