1516322 - MobileViewportManager::ShrinkToDisplaySizeIfNeeded() is broken in RDM on Windows with non WebRender

Status: RESOLVED FIXED

(Core :: Layout, defect, P3)

Description

[Hiroyuki Ikezoe (:hiro)]

STR
1) Enable apz.allow_zooming
2) Open https://hg.mozilla.org/mozilla-central/file/d2bc993e14ea/layout/reftests/meta-viewport/initial-scale-0_5-ref.html in RDM
3) Make sure touch simulator is enabled
4) Reload the html

A green box should be positioned at the top left of the viewport, but actually it's not.

Interestingly this issue doesn't happen on WebRender at all.

Anyway, I am going to skip some reftests that will be added in bug 1423013.

Note that apz.allow_zooming is not yet a supported configuration on desktop, so it is expected that some things will go wrong.

I am adding this bug as a dependency of bug 1461360, which tracks the various issues that need to be fixed before we can enable apz.allow_zooming on desktop.

Now all reftests in layout/reftests/meta-viewport pass on Windows too.

I am going to enabled them on Windows.
