Hangs when starting #590

Closed ghost closed 7 years ago

ghost commented 7 years ago

ScudCloud Version

ScudCloud 1.61
Python 3.6.1
Qt 5.9.1
PyQt 5.8.2
SIP 4.19.2

Distro and Desktop info

Distribution: Archlinux
Desktop environment: GNOME on Xorg/Wayland

Steps to reproduce

Start scudcloud, from GNOME GUI or with CLI
Scudcloud hangs
Popup: “This app does not respond”

More info

On wayland it makes the entire desktop freeze.
I have absolutely no logs or debug info at all, with --debug 1 or in systemd journal
I tried to remove all my config files : rm -r ~/.config/scudcloud. Before, GUI was totally blank. Now I get the slack login page, but it hangs anyway.
It started with QT 5.9
I tried to reinstall all the packages.
Network is very stable and very fast.

Hi @gui-don and thanks for reporting this. Please, check #582. This problem is caused due the qtwebkit upgrade not supporting Slack internal JS/CSS.

Hi @raelgc! Thank you for your scudcloud!

Actually, on #582 , I read that the update qt5-webkit 5.212.0alpha2-1 solved the issue for everyone. Not for me :/ I use qt5-webkit 5.212.0alpha2-4, but it still hangs.

I thought I did something wrong, that’s why I tried to clear the conf. Maybe I can clear some qt cache or something the like that could fix the problem?

Thanks for the additional info, @gui-don. I just re-opened the issue.

I think I fixed the issue. I guess scudcloud has use qutebrowser or at least the same dependencies than this soft. So, according to this source: https://github.com/qutebrowser/qutebrowser/issues/357, the problem could be related to mozplugger.

If the lib is present in user directory, but package absent it makes scudcloud hangs. Maybe I installed the package and remove it afterwards. So I guess it’s a bug in one of the dependencies related to HTML rendering/web browsing stuff, making a test on the presence of the lib to determine if mozplugger is installed or not.

Anyway, either install mozplugger or make sure the lib is absent: rm ~/.mozilla/plugins/mozplugger*.so solved the issue.

Thanks for sharing your resolution @gui-don.

You're right, qutebrowser uses the same web engine as Scudcloud, qtwebkit.
