Comment 2 for bug 132363

I've attached a low-res video demonstrating the slow rendering under compiz, using gqview because it is the best example.

Compiz normal effects are on to start with.

In the video:

1. I open the image. It takes a few seconds to render.

2. I close the image and turn off compiz effects.

3. I re-open the image. You can see it renders much faster - within a second.

It doesn't matter which order I do the test in (ie there isn't any caching going on that could speed things up the second time you open the image). I've done it in this order because switching from no effects to normal effects takes a few seconds.

Note that:

* It is less noticeable with other viewers like eog because they render faster to begin with.

* It is more noticeable when rendering large files. This particular example is a 1 MB jpeg.
