Yes, this does sound video driver related. The compton config change is a
workaround; XRender is far from being the ideal backend for compositing
(the glx backend is usually preferred) but in this case the video driver is
apparently not handling it well. In fact this sounds like the bugs I had
using compton+glx under VMware video emulation that went away when I ran
directly on the hardware.

I used to have that problem, turning off terminal transparency helped. Not a fix but at least a workaround. I suspect the video driver because it was a change in driver that caused it, if I recall correctly.

Hello
I've been a long-time xmonad user (over 5 years) on all my machines, installing using the Debian package.
I'm currently running Debian jessie kernel 3.16 on my main desktop.
Recently I upgraded Debian on my primary desktop (jessie kernel 3.16). I'm running xmonad v0.11, instead of v0.10 on my other machines.
I notice that when certain GUI application are running (e.g. Chrome, vmplayer, but not firefox & thunderbird) my urxvt terminal renders *really* slowly, redrawing the window line at a time! I also notice a huge X server CPU load (25-50%, as shown by top).
I've looked at X server logs and config and cannot see anything that is unusual.
Could there be an xmonad issue here? Has anyone else experienced something similar? Any hints as to how to debug this?
