Dear all,
After a recent DU, Firefox is incredibly slow, for instance, when scrolling it lags almost a second before the page actually moves.
I created a new user, using Firefox fresh with no plugins, in a plain HTML page (no scripts, flash, ads, nothing) and I still have this problem. I tried it in Plasma and in fluxbox, with the same result. The memory and CPU usages do
not go high when using Firefox.
Chromium runs just fine.
This started happening right after a recent DU. Here are my logs for that DU:
http://paste.siduction.org/20160724090508I suspected the new xorg-core, but I see no errors in Xorg.0.log:
http://paste.siduction.org/20160724090732Since a new kernel also came, I also tried an older kernel, but it did not help. (I see no kernel.log in /var/log/. Is that normal?)
I have no idea where else to look for problems.
Here is some info on the laptop:

P.S.: I thought of putting this on Upgrade Warnings, but since I am the only one who seems to be having this problem, I thought maybe Software would be better. Mods, feel free to move this if it seems appropriate.
