New info:
Today I've witnessed such situation - opening a new tab, but the hint from first tab appeared over the second after maybe 1/2 of a second.
I think it is somehow connected.

Attachment: The hint is on all other tabs

Okay. I don't know what influenced it, but here are some new facts.

I had some problems with my CPU cooler, and had to limit my CPU to 90%.
And when I've installed new cooler, I've removed that limit, and the "hints all over browser" were gone.
I've tested for 3 days, and haven't noticed any of them. But now I've had one again!

Added a video where this bug shows itself.

This bug is actual for 69.0a1 nightly and with enabled WebRender too.
Got new videocard, reinstalled Win10 and drivers - no effect.

Wow, now I've opened a tab while building android project (whole CPU was used) and the hint was shown like after 7-8 seconds after tab was opened. And, of course, it won't go away.

Hi Revertron,

We are unable to reproduce this issue even with WebRender enabled, but maybe you can provide a bit more info.

Can you please download Firefox Nightly from here: https://nightly.mozilla.org/ and retest the problem and see if the issue still occurs there as well?

Does this issue occur with a fresh profile? you can find the steps here: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager

You can also try turning Content Blocking off and retest this issue, from the Site information panel on the left of the URL bar > click the Turn off Blocking for this Site and see if the issue goes away.

Looking forward to your answer, Florencia.

Hi Florencia,

I am using Nightly as my daily driver, and update it 1-2 times a day. And the bug was present as long as I remember.
I've tried a clean profile as you suggested. As you can see, the bug is there: https://up.zbin.eu/Gw9kra.mp4
It took about 20-30 link openings but finally it revealed itself.

Is it fixed now? (with latest https://nightly.mozilla.org)

Comment 10

[Revertron]

Did anyone try to fix it?
I see it every day. Last time 3 seconds ago. On current nightly.

In your profile, does this select the new tab immediately?

In your profile, does this select the new tab immediately?
Yep, very quickly.

Comment 13

The video shows the tooltip from the original page appearing after the new tab was switched to, so that looks like a problem with the timer in nsXULTooltipListener.cpp.

Comment 14

[Revertron]

Just updated the Nightly, and can't repeat the bug.
I will take an eye on it.

Comment 15

[Dão Gottwald [:dao]]

Sounds like bug 1550637 fixed this then, although I'm not sure how it would have done that for the case where the tooltip would appear after switching tabs.

Comment 16

[Revertron]

Nope, not fixed :( Appeared just now again :(

[(No longer employed by Mozilla) Aaron Klotz]

I can still repro as well, typically with tooltips from treeherder.

FWIW I'm on current Nightly (2019-06-18, so after bug 1550637 landed) and still encountering this.

Comment 19

[Revertron]

Yep, this bug is not fixed, as #1550637, I think.
