[Hartmut Welpmann [:welpy-cw]]

Steps to reproduce:

Actual results:

Popup menu opens, but is inaccessible by mouse, neither following the mouse cursor nor accepting clicks.

Expected results:

Popup menu opens, follows mouse cursor and reacts to mouse clicks.

Interestingly, the same popup menu does work in the "Search Messages" window, which happens to be non-modal, see attached screen caps.

Running mozregression gave the following result:

The corresponding regression range in mozilla-central seems to be https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=9d96d2c96d8fe1d9365fdaee30d8fda048c48aa1&tochange=8e6dd71c4ece68ea8667d0e75488023b502bca76.

Maybe a regression in connection with fixing bug 1807482?

Does this happen in other desktop environments? That bug shouldn't have affected xfwm. https://hg.mozilla.org/mozilla-central/rev/47c002d3637247e71ee901f32421deaecc9d8ea3 is probably a better candidate, but hard to say... would there be any chance of narrowing that regression range?

I tested Ubuntu 22.04 (Gnome/Mutter) as well as Kubuntu 22.04 (Plasma/KWin) in virtual machines, exactly the same behavior.

Unfortunately I have no idea how to further narrow down the regression window, as so much change sets have been pushed together ...

Just for the record, the same builds work flawlessly under Windows, so I assume it's some Linux-specific change that's responsible.

Comment 10

[Hartmut Welpmann [:welpy-cw]]

So I cloned revisions 9d96d2c96d8fe1d9365fdaee30d8fda048c48aa1 of mozilla-central and ff5b4d8b5e79413d68982721a4bc76c9fcadacc1 of comm-central and built Thunderbird completely. As expected the popup menu works flawlessly. Then I imported just the raw diff from https://phabricator.services.mozilla.com/rMOZILLACENTRAL6b9b8523de07f62b35b94c63e2b93cf995c440f7 and built again. The resulting binary actually shows the erroneous mouse behavior, so that commit seems indeed to be the problem.

Huh, so gtk_grab_add does have a useful effect? That's rather surprising.

The patch landed in nightly and beta is affected.
:welpy-cw, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta approval.
• If no, please set status-firefox110 to wontfix.

For more information, please visit auto_nag documentation.

I am not sure, TB 111.0b1 is expected in eleven days and Firefox doesn't seem especially affected. What do you think, :mkmelin?

Comment 19

[Magnus Melin [:mkmelin]]

It would seem good to uplift to beta, but not critical.

This is too late for beta as we build our RC today and I think we don't have a good enough benefit/risk ratio to take just before the merge. I am morphing the request into a release approval request and we'll reevaluate for a potential inclusion in our planned dot release, thanks.

This patch is now on 111 beta and the Thunderbird 111.0b1 should ship soon, I think this should just ride the 111 train, thanks.
