I’ve upgraded to 13.1 RC, and I have a strange problem with browsers going to 100% CPU and freezing the system. I’ve tried Firefox, Opera, Chromium and qtwebkit (Qupzilla and Rekonq), and there is one site that consistently causes them all to go to 100% CPU and slow/freeze the system. (I can’t link to it because it’s the admin area of a website). It’s not as bad on all sites, but CPU is generally high for them all.
The only obvious thing linking those browsers I could think of was flash, but the problem persists after removing that.
I presume there must be a shared library that they all use that’s causing the problem. Maybe sqlite for history etc. is the common element?
Does anyone know how I could identify the cause?
