972566 - Panels aren't correctly anchored after resizing the anchor's window

Status: VERIFIED FIXED

(Toolkit :: UI Widgets, defect)

Description

[Sevaan Franks [:sevaan]]

I was playing around with the first-run tour experience for Australis, and decided to resize the window while the tour was running. Sometimes it resizes fine, and other times some of the tour elements hang.:

Sometimes they persist until I resize the browser again, and sometimes it redraws after a short period of latency.

Running: 30.0a1 (2014-02-12) on Mac OSX 10.9.1

I've seen the latency before but I haven't noticed it get stuck in the wrong position like that.

It sounds like this is only after resizing so P4?

Thanks for the report

Hey Matt, I can get it to persist after a few rough resizing back-and-forths. Once I interact with the window again, then it corrects itself.

According to bug 969350 comment 4, this is reproducible 100% of the time on Linux.

Neil, is this something you can take a look at?

nsXULPopupManager::AdjustPopupsOnWindowChange is getting called when I resize on Linux but it seems like layout isn't getting told to redraw until I interact with the window in some way.

Attachment: patch in progress

This patch fixes the issue on Linux. It changes to call AdjustPopupsOnWindowChange during the other WindowResized listener, after it reflows the content. This might not work though on platforms that don't have both listeners, so I need to investigate a bit more.

I think the original Mac issue is a different problem though as I think in this case the repositioning is done at the os level there.

I don't really know what the difference between the webshell and view resize is nor am I clear as to how I could test the code so I'd prefer if someone else looked at it.

Why not cut out the middle man and call pm->AdjustPopupsOnWindowChange(presShell->GetDocument()->GetWindow()); directly?

"Help > &brandShortName; tour" will open the tour then just resize the window

Ah, that makes sense if the panels are anchored to content that we need to process the resize of the parent window and move the anchored content before repositioning the popups.

Hey Neil, are you planning on uplifting this? We should get it uplifted soon if possible.

[Triage Comment]
Given this is low risk and improves the UI tour we definitely want this on the first Australis release so please uplift to beta as well unless the patch doesn't land cleanly in which case nominate a new patch for that branch only.
