Title:
System runs out of memory - white
Marcos, what probably happened is that during those 8 hours that the app
was in the background your device ran low on memory at some point, and
the system decided to kill the oxide renderer process to free up some
memory. The way to go in that case is to monitor webProcessStatus, as I
suggested
Hi Olivier :)
I found a behavior: Open uNav and put in background. Open it after
8hours and uNav will have a white screen (because it hasn't that
webview anymore, I don't know why).
I saw some apps, like Telegram, are reloaded when they come from
background, but it is not a new fresh start.
I agree, reloading the webview (thus most probably loosing the current
navigation state) wouldn’t be great. Displaying an error message would
at the very least give some useful feedback to the user, as opposed to a
plain white view.
Of course this is not enough, we need to understand where the
Monitoring webProcessStatus and then doing a reload if the process is
killed by the system is probably ok for most webapps, but this isn't
great for a navigation app. What happens to the state of the current
navigation if the render process is killed and the webview has to be
reloaded?

I'm experiencing the same problem mentioned by Marcos, from 2/3 OTAs now. In my

uNav is doing a lot of calculations by second when you're driving.
Then the CPU usage is so high.

@Marcos: what do you mean by "uNav is generating a lot of

IIRC I once suggested you to monitor the 'webProcessStatus' property of
the webview, and offer some user feedback when it’s killed or crashed.
It doesn’t look like anything like that is implemented in uNav. You can
take a
Hi, IMO this persists in RC-proposed.
uNav has a white page when you return from another to it. uNav is generating a
lot of process/second.
Thanks in advance!

"white screens" while using the app is pretty extreme: it means that the
renderer gets killed while the app runs, as opposed to the oom killer
getting rid of a dormant app to free up some resources for the foreground
tasks.

Recent reproduction notes (on OEM bug #1490529 )
Scrolling in webapps can cause white screen not being able to scroll
anymore.
Product: Krillin bq Aquaris E4.5, E5

HW version: MP
Actual Result:
FB & browser screen go white after scrolling a while.
Expected Result:
Facebook
I think this bug should be de-duped, and re-opened.
the behaviour is back, and the fix in bug #1376165 seems to have been
insufficient :-)

Client apps should definitely not quit if the render process quits, as
that kind of defeats the purpose of having isolated render processes (if

Bugs,
after some discussion on IRC, this isn't a memory leak.
however, this is more like a request for memory optimization of unity8
dash/scopes etc.
according to the guys doing the testing
they see ~45% mem consumption due to unity8-dash, but then it settles to ~12%
thinking its due to swap.
So is
12% is when idle after a reboot and without any additional scopes other
than the default ones. It seems that adding custom scopes to the dash
makes the memory usage grow significantly.
