1526217 - [snappy][Ubuntu 16.04 GNOME][CSD] Window cannot be resized with cursor and has no shadow with Ambiance theme

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

[Kestrel]

The Snap package beta 66.0b6 with Ambiance theme on Ubuntu 18.10 does not allow the window edges to be resized with the cursor, the cursor icon does not change on hover over any of the window edges and clicking and dragging does nothing. The window also doesn't have a shadow which usually comprises the resize zone. Turning on the system titlebar restores functionality.

Resizing works and shadow is rendered with the Adwaita theme (also used as fallback for Yaru).

Most likely caused by Bug 1521012.

I can reproduce this with latest Nightly 67 on Ubuntu 16.04 (Snap build environment) with ubuntu-gnome-desktop installed and Ambiance theme. Other applications have the same problem, Ambiance theme appears to be broken on GNOME Shell in 16.04 and this is carried through in the Snap.

On Nightly 67 it does not occur with mozilla.widget.use-argb-visuals defined regardless of value.
On Beta 66.0b6 it does not occur with mozilla.widget.use-argb-visuals = false.

Regressed by Bug 1521012.

Hey Jimm, should we still be tracking this for 66?

This has been fixed on Ubuntu 16.04 with GNOME desktop by Bug 1529713.
