HTML5 games as webapps hang hard after a while

[Oliver Grawert]

Playing the fruity-pops game from the store on the phone it reliably hardlocks between level 11 and 14, the browser UI hangs hard usually in the middle of an animation (memory leak ??).

watching with top while this happens, there is definitely no memory leak. QtWebProcess consumes around 80% CPU constantly through the game without rising or dropping, the same goes for the memory consumption which lies between 76 and 80MB
once the hang occurs the QtWebProcess as well as webbrowser-app are gone from top.

the phone gets very warm then, even though top does not show any runaway processes or big CPU consumers.

I managed to get a crash of QtWebProcess while attempting to play this game, unfortunately the backtrace is corrupted, nothing interesting there. I’ll give it another spin.

I managed to make it hang this time without a crash.

Note that I’m still seeing QtWebProcess and webbrowser-app in the output of ps after the hang, so it’s definitely not a crash.

Since we've moved to Oxide, I think this bug is now invalid.
