gnome-terminal transparency spikes X cpu utilization even when windows is rolled or minimized

Description of problem:
When transparency is turned on in gnome-terminal X cpu utilization should be expected to rise if your dumping a text file to stdout. However, when that window is minimized or rolled, X continues to utilize the exact same ammount of CPU even though its not actually rendering anything to screen.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Set transparency to a 50% value.
2.Cat a large text file in a gnome-terminal with transparency on.
3.Minimize window (or roll it up).
4.X CPU use stays the same.
5.Turn transparency off.
6.Cat the same file, X CPU use is lower as expected.
7.But when you minimize the window (or roll up) X cpu use appears to decrease
Actual Results: X uses CPU when it doesn't seem like it should need to. Is this a bug in X or is gnome-terminal sending X data it doesn't need?
Expected Results: X cpu use should go down when there is nothing on the screen for it to render (ie; a minimized windows having text streamed to it)
This is actually a vte bug (the rendering widget used by gnome-terminal), not a
gnome-terminal bug. I'm going to reassign.
Please be sure to file this upstream at bugzilla.gnome.org, because this task is
not something Fedora has engineering resources to prioritize.
