blocky text in skia ozone demo code on eve

Project Member Reported by spang@chromium.org, Apr 26 2018

Issue description

Running skia_demo on eve results in corrupted output. The "Hello Ozone" text is corrupted for about half of the rotation and looks fine in the other half.

There may be a synchronization issue.

See attached screenshot.

Repro steps:
  cros chrome-sdk --board=eve 
  ninja -C out_$SDK_BOARD/Release -j1000 -k50 -l32 ozone_demo  chrome chrome_sandbox  skia_demo
  deploy_chrome --board $SDK_BOARD --to $IP --build-dir out_$SDK_BOARD/Release --nostartui
  scp out_eve/Release/{ozone_demo,skia_demo} root@$IP:/opt/google/chrome/ 
  ssh -t root@$IP /opt/google/chrome/skia_demo

Seems skia doesn't load fonts on device correctly. I am not familiar how skia handle fonts?

Hi robertphillips@ & egdaniel@, could you please give us some suggestions?

The fonts load, it just renders badly. If you try it you'll see the fonts render correctly sometimes, and other times as black squares.
