Thank all for reporting this issue.

I remember a similar issue in the past. Usually this breaks other clients too, so they revert the change in some hours.

I restarted Scudcloud here, and I'm not seeing this issue.

Still an issue for you?

@raelgc I just started scudcloud again and yes it is still an issue (or maybe an issue again) for me.

Same for me as well - broken after restarting. Not sure if this is relevant but I applied some updates this morning before opening Scudcloud. Yesterday everything was fine. The updates were:

Hm, I think I've found the reason why it's not broken in my system: I've installed (to test) KDE Neon some days ago. So my Qt and PyQt was upgraded to 5.7.

There is a package to update only the qt-webkit in Ubuntu 16.04: http://repo.paretje.be/pool/universe/q/qtwebkit-ng/libqt5webkit5_0.0.0+tp5-1~ubuntu16.04.1_amd64.deb

Yep, installing that package fixed it for me on Ubuntu 16.04 @raelgc

I'll try get the source package and try to build it on Launchpad, in order to get everyone using the PPA receive it as automatic upgrade.

@raelgc raelgc commented Jun 15, 2017

Hm, this package has some deep Qt dependencies. Works fine with Ubuntu and Unity (and probably all other GTK desktop environments). But I'm wondering if, forcing the upgrade using the PPA can break Qt environments dependencies using other versions.

Hm, finally I got able to build it for xenial-backports. Are you guys all in 16.04.2?

@n8willis n8willis commented Jun 15, 2017

Has anyone tried dropping in the qtwebkit update on Ubuntu 16.10? Because this certainly is affecting my 16.10 system; I'm not super excited about the idea of plugging in a standalone .deb for a single package (too many bad memories of RPM hell), but if there's no other way and Slack isn't reverting the change ....

@raelgc — as implied, I at least am on 16.10 :)

@raelgc raelgc commented Jun 15, 2017

@n8willis What is great about the solution proposed package is it's only an update for qtwebkit.

You can find zesty version here: http://repo.paretje.be/pool/universe/q/qtwebkit-ng/libqt5webkit5_5.212.0-alpha-1~ubuntu17.04.1_amd64.deb

But I was not able to find a yakkety version.

Anyway, sometimes I wonder if we should change to an Electron base. Sure, more memory usage, but at least, an updated and more stable web container.

thanks very much @raelgc . updating qt-webkit on my Ubuntu 16.04 fixed the problem.

@n8willis n8willis commented Jun 16, 2017

@raelgc I'm clear on what the proposed solution is; what I don't like is dropping in a single DEB acquired from outside the repository, because that has a tendency to interfere with smooth repo-based updates of dependent packages & libraries further down the line.

Are you saying there's no hope of it building for yakkety?

@raelgc raelgc commented Jun 16, 2017

@n8willis yeap, I suffered from bad packages in the past too.

There is no built package for yakkety, but I think I can install yakkety in a VM and build it using the sources.

@n8willis n8willis commented Jun 16, 2017

@raelgc Cool; happy to test it if it builds. A yakkety DEB is far preferable to a Xenial or Zesty one, that's for sure!

@tigerand tigerand commented Jun 16, 2017

this is really not a great solution. the package for a particular release should be built against, and depend upon, libraries available for/from that release. how could i have installed scudcloud package for xenial release when it should depend on libraries i don't have and aren't available? the install should have failed with unmet dependencies. having to download (and trust!) some arbitrary package off the web, then install it with dpkg -i, well, that's no way to go through life, son! -from Animal House

@raelgc raelgc commented Jun 17, 2017

@tigerand To explain: Slack updated their internal CSS and webkit (the HTML engine Scudcloud uses) include in Xenial cannot handle this new CSS properly.

I'm pointing, for now, for a package that has builds for xenial and zeist. This package will update the webkit in your system.

I'm balancing the pros and cons about put it in the PPA. I'm afraid that, while I can fix Scudcloud for some users, I can break other systems relying in the same technology.

I'm totally open for other ideas.

Upgrading to Qt 5.7.1 fixed it for me as well on Gentoo ( from Qt 5.6.x were it was broken ).

Same problem here on Debian Jessie. Not sure if it'd be wise for me to upgrade the Qt lib though.

Solved the issue on Linux Mint 18.1 Serena (Ubuntu 16.1) by installing the 16.04 DEB package (!): http://repo.paretje.be/pool/universe/q/qtwebkit-ng/libqt5webkit5_0.0.0+tp5-1~ubuntu16.04.1_amd64.deb Got a slightly odd message that implied I'd already installed it, but it worked! Thanks to everyone who's been commenting on this as the "white screen" issue has been bugging me for a couple of weeks now.

@raelgc the package given by @Richard-ES doesn't work on Debian, it need more dependencies that doesn't exist in Debian.

Dependencies are an issue for the long chain in qt-webkit. Wondering if we should try build a flatpak/snappy version of it.

Ok, finally I got able to create a source package for the updated webkit and upload it to the PPA. For those who didn't install the deb file, this will fix:

sudo apt update && sudo apt dist-upgrade
