WPEWebProcess Constant 80-90% CPU Usage

I am working on porting my existing chromium based project to use cog on an embedded linux device. I successfully built cog and its dependencies using the latest meta-webkit from yesterday:

I am using Weston on my device and chromium's performance is adequate. However, when I try to use cog, it does render in full screen the display, and the virtual Weston keyboard works, but the performance suffers badly due to a constant 80-90% CPU utilization by the 'WPEWebProcess' process:

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND

I am starting cog with the following commands:

export COG_PLATFORM_WL_VIEW_FULLSCREEN=1
export COG_PLATFORM_WL_VIEW_MAXIMIZE=1
cog --ignore-tls-errors -P wl https://google.com

I must be doing something wrong... What can cause the CPU to be constantly taking 80-90% when I am not interacting with the page, just rendering Google? Thank you very much for any help.
