GD Image Filtering Low Quality / Poor Performance
The installed version of PHP GD does not support image filtering(desaturate, blur, negate, etc). It was probably compiled using the official GD libraries from http://www.libgd.org instead of the GD library bundled with PHP. You should recompile PHP --with-gd using the bundled GD library. See http://www.php.net/manual/en/image.setup.php. An implementation of imagefilter in PHP will be used in the interim.
GD Image Rotation Low Quality / Poor Performance
The installed version of PHP GD does not support image rotations. It was probably compiled using the official GD libraries from http://www.libgd.org instead of the GD library bundled with PHP. You should recompile PHP --with-gd using the bundled GD library. See: http://www.php.net/manual/en/image.setup.php. An implementation of imagerotate in PHP will used in the interim.

It could be that I found the problem, I had Webform Reports enabled and it seems to have been interfering with some other modules. I will do some more testing to find out.
