Problem with Jessie, Chrome, and Icedove
I had a bug when I installed Jessie, and I'd like to finish confirming it.
This is happening on a Dell Optiplex 620GX with 2 gigs of RAM, and a dual core processor on the CPU. It also has an Intel graphics adapter onboard. It's a pretty common workstation in the corporate world, so I'm surprised that it's not working with Jessie.
There are two issues:
1) The GPU process in Google Chrome takes up 50 percent plus of the CPU utilization - not memory, CPU utilization - and on both cores. Nothing else can run, or one of the CPU cores will saturate and the computer slows to a crawl.
2) Additionally, when I run icedove (Thunderbird) by itself, I get one of the CPU cores at 100 percent utilization, and the second one runs between 30 and 50 percent utilization. I can't run Chrome at the same time, and in Wheezy I used to have those two idling in the background while I'm working in foreground with whatever.
Using the --disable-GPU command line parameter in Chrome cures the problem somewhat with Chrome by itself, but it's not a panacea. Short of recompiling icedove, I haven't found anything yet that fixes the problem with icedove.
Anyone have any idea what changed from Wheezy to cause this?
