Title: otter v 0.9.11 some HTML5 pages crashing
Post by: mad_king on 2017-06-29, 07:35:47
I have build otter 0.9.11 for iMX6 soloX linux
Below are some random errors observed for some HTML5 pages and page crashed. Error observed approximately after 1 hour (not instantly when switching pages). one more observation, QtWebengineProcess exited (/usr/lib/qt5/libexec/QtWebEngineProces).

Some pages are working fine without any problem. Also tested same code for ubuntu 14.04 and works fine. I am using Qt 5.7.1 and otter build with QtWebengine

Is this same problem mentioned here (https://bbs.archlinux.org/viewtopic.php?id=214026)?

Errors on console -

@mad_king, try reproducing that using:
https://github.com/OtterBrowser/test-qtwebengine
It looks like some sort of QtWebEngine issue.

Also you should update to at least beta 12 (0.9.12) and consider testing using Qt SDK 5.9 (official Qt binaries).

Thanks for valuable inputs.
Using test code i could able to reproduce the said issue. It seems something goes wrong with QtWebengine.
As per this link (https://bbs.archlinux.org/viewtopic.php?pid=1639729#p1639729) this is related to GCC 6. First i'll check with this workaround.

Thanks

@kanakomoerer, what exactly is broken there?
Some images showing broken and correct rendering could be a good idea, I could use them to ask upstream developers.

After detail investigation, this is not a qtwebengine (eventually not Otter) problem. This is related to RAM (with hardware and build system). Now it works as expected.
@Emdek - Please mark it as solved.

Thanks

@mad_king, I see.
Well, we not use such prefixes here (like [solved]), that's more suitable for tickets system. ;-)
