Comment 6 for bug 1480654

Bisected. Actually, trisected. There were three separate regressions to input and focus (one of them fixed), and we're now seeing the cumulative effect of the other two.

First regression: r2590 slightly broke focus changing such that the focus change is sometimes withheld and delayed until your touch gesture in the old window finishes. It doesn't matter how long your gesture takes, since r2590 Mir would delay the focus switch till the gesture is completed (fingers raised).

Second regression: r2652 broke touch input completely. It did not work at all until fixed in r2656 (LP: #1464174).

Third regression: Some combination of r2652-r2656 created the behaviour we see today. That is the focus change takes effect immediately but touch events are ignored for about the first second after the focus change. I can't tell which revision caused the exact problem because the second regression remained unresolved during this time so there was no working touch support to test with.

The exact offending revisions to investigate are:
