[Bug 1659435] Re: browser stops rendering all pages instead shows new tab page

[Olivier Tilloy]

The new tab view is superimposed on the webview when newTabViewLoader.active is 
true.
When switching tabs, the following code (in Browser.qml) is responsible for 
unloading the new tab view if the tab we’re switching to has contents loaded:

Connections {
  target: browser
  onCurrentWebviewChanged: {
if (currentWebview) {
  var tab = tabsModel.currentTab
  newTabViewLoader.active = !tab.url.toString() && !tab.restoreState
}
  }
}

I’m not seeing any indication in the logs that this code fails to be
executed.

Attaching video demonstrating the issue, courtesy of Bill.

It’s clearly the new tab view that is incorrectly being overlaid on top
of the actual webview. This apparently happens when clicking a link that
opens a new tab, although there must be another factor at play because I
haven’t been able to observe the issue myself.

I initially thought the following error could be related:

  file:///usr/share/webbrowser-app/webbrowser/TabComponent.qml:259:
ReferenceError: tabContainer is not defined

but apparently not, as I’m getting it too without observing the issue.

Hit this again, looks like oxide-render processes are running 
http://pastebin.ubuntu.com/23912354/

Here is log from browser:
http://pastebin.ubuntu.com/23912358/

The problem occurred clicking on a link in a gmail message which attempted to 
open a new tab.
Note that I can long press on a tab and open in a new window and it renders 
correctly. I can also create a new private window and that works correctly, so 
seems to be an issue only with the main window and not oxide rendering per se

[Bug 1659435] Re: browser stops rendering all pages instead shows new tab page

[Olivier Tilloy]

I’ve just spent ~an hour browsing many different websites with many tabs
open in a unity8 deb session, and haven’t experienced that issue. I’m on
a fully up-to-date xenial+overlay machine.

I’ve seen the same errors in the logs when clicking links that open in
new tabs, but no visual problem, so they seem to be red herrings.

It's happened 3 times in last hour, fwiw

Seeing multiple of these messages after the problem starts:

[0125/171219:ERROR:layer_tree_host_impl.cc(2189)] Forcing zero-copy tile 
initialization as worker context is missing
[0125/171219:ERROR:oxide_compositor_gpu_shims.cc(258)] Error creating EGLImage:
