Bug description:
Seems that the dash gets resized() very shortly after its created.
This seems to cause a degradation from "triple-buffered" operation to
"double-buffered" operation. On some device loads (eg, krillin+dash,
where the rendering needs to be triple buffering to stay at vsync
rate), this can cause the performance to dip
tagging as critical, as it should block 0.23.
