This tweak gets rid of the diagonal stripes that show in the details area of the games list under certain conditions.  It's a completely optional thing; it is only included in case you really don't like those stripes.  Keep in mind that for some games or in specific conditions, the stripes are the only image that shows up for the background of the details, so not having them might make the details pane feel a bit bare.

To apply the tweak, just copy the contents of this folder into the halinads skin folder, overwriting existing files/folders.  If steam is running, you will need to restart it for the changes to take effect.

If the tweak did not work, then you copied the files to the wrong location.
