1557275 - [wayland] reordering tabs within a ff window doesn't work

Status: RESOLVED DUPLICATE of bug 1527976

(Core :: Widget: Gtk, defect, P2)

Description

[luis.pabon]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:69.0) Gecko/20100101 Firefox/69.0

Steps to reproduce:

Ubuntu 19.04, firefox-trunk from mozilla ppa (69.0a1hg20190604r476795-0ubuntu0.19.04.1~umd1), sway 1.1.

• env MOZ_ENABLE_WAYLAND=1 firefox-trunk
• Open a bunch of tabs
• Try to drag them around to reorder (within the same window)

Actual results:

Nothing.

Expected results:

Tabs can be reordered.

This is not the same as https://bugzilla.mozilla.org/show_bug.cgi?id=1527976 - that bug is about detaching a tab into a new window (which also doesn't work).

I've seen this as well, it doesn't occur all the time (and might take a while to stop working). I THINK how I've triggered it in the past is to switch to external monitors (dock) and then dragging stopped working. May also have something to do with multiple windows (I typically have at least two ff windows open).

I think it's related to wrong droparea size which is stored in nsWindow. I spent some time with this and going to look at it more.

Btw. this is the same bug as 1527976 - the drag does not start because due to broken drag area coordinates.

This one has regressed upon upgrade to 69.0a1hg20190620r479697-0ubuntu0.19.04.1~umd1.

It is a sway issue where drag and drop randomly stops working. Restoring ticket state as it was before.
