WebView::GetLocationBarContentOffset() returns -nan.
I’m not sure where the root cause of the issue lies
(cc::CompositorFrameMetadata::top_controls_height and
cc::CompositorFrameMetadata::top_controls_shown_ratio having non-number
values), this would require further investigation to determine. The
following patch works around the issue:
float WebView::GetLocationBarContentOffset() const {
float offset = compositor_frame_metadata().top_controls_height *
compositor_frame_metadata().top_controls_shown_ratio;
if (std::isnan(offset)) {
return 0.f;
}
return offset;
}
Note that the code for the location bar controller has been
significantly reworked in oxide since then, so it’s hard to tell whether
the issue (which doesn’t exhibit in master) has been fixed in oxide
itself or whether it was a bug in chromium that has been fixed since
then.

Title:
oxide 1.18.3 crashes when running webbrowser-app tests
Status in Oxide:
New
Status in Oxide 1.18 series:
Confirmed
Bug description:
After upgrading oxide-qt from 1.17.9 to 1.18.3 I’ve started observing
consistent crashes when running both autopilot and unit tests for
webbrowser-app.
Steps to reproduce, on a system running xenial+overlay:
$ bzr branch lp:webbrowser-app
$ cd webbrowser-app
$ cmake . && make
$ ./tests/unittests/qml/tst_QmlTests -input
tests/unittests/qml/tst_UbuntuWebView02.qml -import src
Here is a stacktrace I get:
