@jeroen: I tested CSS Tidy, but that doesn’t work either.

Hey,
The problem is in the relative Image path. you have something like

url(images/post-bg.jpg)

in your CSS. Plugin will combine the CSS so it would be one file and will load from

static.mysite/site/w3tc/min/

so the calculated path for the above code would be

static.mysite/site/w3tc/min/images/post-bg.jpg

The only thing I could say is just turn the CSS minify off and try to replace full path in your CSS files, then enable it again.

@psionmark – Did you find any solution?
I have the same issue with my blog! ??
What should I do in order to get lower GPU usage in MT???
I know 1blogcacher can do that but it causes very problem such as Internal server error.
