Firefox slow after uprading on Fedora Linux, --safe-mode and refreshing don't solve it
Hi All, I've dist-upgraded my Fedora 23 to 24 this morning, and Firefox is very slow to the point of not being usable on the upgraded system while everything else is fine (I am writing this using Chrome).
The peformance of Firefox was decent on the system before upgrading.
Running in safe mode or refreshing Firefox as described at https://support.mozilla.org/en-US/questions/1121351 does not improve performance. Re-installing from the Fedora packages doesn't either.
To give you an idea of how slow it is, imagine I click in the URL text box and do CTRL-A: it can take up to 4 seconds before I see the URL text being selected.
I've documented the issue also at https://bugzilla.mozilla.org/show_bug.cgi?id=1293268 .

An update: Firefox is slow only in i3wm, my window manager of choice, but its performance is ok in Gnome. This suggests that the issue is related to something the two window managers do differently, and there's a lot of it :-(
I've notified the i3wm user group on Reddit too, but so far no luck https://www.reddit.com/r/i3wm/comments/4wqwcf/why_would_an_application_run_slow_in_i3_and_fast/ .
So it looks like the issue is in a recent Linux kernel bug with Intel drivers, read more at https://bbs.archlinux.org/viewtopic.php?id=213533 . Some people got workarounds working, like running composite managers even when they're unnecessary, as in my case, running i3wm.
