1990665 - Wrongly positioned popups and misaligned cursor hover in menus (KDE)

Status: RESOLVED DUPLICATE of bug 1977547

(Core :: Widget: Gtk, defect, P3)

Description

[gudvinr]

Attachment: tab tooltip

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:143.0) Gecko/20100101 Firefox/143.0

Steps to reproduce:

I open up burger menu and it opens closer to the middle rather than under burger button.

Same thing happens with tab tooltip.

It doesn't happen always though. Browser restart "fixes" the issue but after some time it might start happening again

Here's extension menu that is out of place

[gudvinr]

In the extension attachment you can see that under mouse pointer it is not highlighted. You can only make this item actionable if you move pointer to the left. if it's too far right, it's not actionable (even gear icon).

Same if you move pointer too far down in this menu. Extensions at the bottom are not being highlighted on hover.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Can you use mozregression to find broken commit?

DisplayCount	2
Display0	"6144x3456@60Hz scales:2.000000|2.000000"
Display1	"1440x2560@60Hz scales:1.000000|1.000000"

Does it still happen with a single display without any scaling?

I could try but:

• It's not consistent. It might appear and might not appear. So I'd need to sit for prolonged time under single run. Not an issue per se but will make it quite annoying
• I don't exactly know when it started to happen. Maybe after 142, maybe earlier. So I don't really know how to find first good release.

I don't have 6k display at 2x scale though. It's 3840x2160 @ 125%

Does it still happen with a single display without any scaling?

As I said, it's not consistently reproducible, so it'd suck to sit here with just single monitor tbh.

I think its dupe of Bug 1977547.
