This is probably related to a BeginFrame perturbation issue.

tasks_per_frame_ etc. should not be affected by begin-frame issues I think. Re-opening, and /cc+ nzolghadr@, sahel@ from the input-team; we have had a lot of regressions on input around that time. I wonder if this could be related to that.

Passing along to nzolghadr@ as I'm not actively looking at this at the moment.
