Description Wnereiz Z 2019-02-12 06:24:00 UTC

Environment:

openSUSE Tumbleweed, dist upgraded to snapshot 20190205

MozillaFirefox-64.0-1.4

Steps:

1. All add-ons disabled.
2. There are some web pages on different tabs.
3. In a slow network environment, open a website (eg. wikipedia.org) in new tab. 4. While it is still loading, switch to another tab.

Results:

The pages on other tabs will automatic reloading.

Tried on a fresh installed TW instance, the problem existed. Searched on bugzilla.mozilla.org and did not find any similar issue.

BTW, it is on Gnome.
Maybe just because it is slow, or display latency?

I found sometime after I close a tab with a web page just refreshed, firefox switched to another tab automatically, that page was in reloading status.

I found this issue is only occurred on GNOME. (I have check on KDE, it did not show the issue). So I re-assign it to GNOME team.

BTW. It is more likely a performance issue rather than logical bug.

Please try fontconfig packages from
https://build.opensuse.org/package/show/M17N/fontconfig
If that solves the problem, this is not a GNOME issue.

I can confirm the behaviour for XFCE (and the dependency from fontconfig) too 

After installing snapshot 20190209 Firefox became unuseable. Stumbling over 

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=909818
and
https://www.preining.info/blog/2018/10/firefox-got-maniac/

I rebuilt 
fontconfig-2.12.6-2.4.x86_64
and 
fontconfig-32bit-2.12.6-2.4.x86_64

from another (older) installation and with those applied everything went back to normal.

Please reopen if not fixed by fontconfig package from M17N (https://build.opensuse.org/package/show/M17N/fontconfig).

Thank you, the fix works. One tip, it need not only fontconfig package, but also libfontconfig1 to be installed.
