FPS drops dramatically with tilable StaticImage

[SupSuper]

When using a StaticImage with a 1x2 tilable graphic, the FPS rating drops dramatically. Why, and how do I stop this from happening?
Btw, I'm using the CEGUI from CVS HEAD.

The more copies of the tile you draw, the more you will suffer in the performance department. This is just the way things are. You might consider creating a larger "pre-tiled" image, and then have that tiled within the window, since the base image is larger less copies will be needed and performance will suffer less.

Thanks, I made the tilable image 50x50 and now it doesn't affect performance. However, there's this odd occurance:
In 800x600, the image looks fine (its the green dark lines on the sidebar, below the timer and such):

However, in another resolution (eg. 1024x768), the lines look very odd:

Is this intended behaviour? The single greener line (below the timer buttons, only tiles horizontally) looks fine on both.

It's likely an issue with either auto-scaling and/or tile alignment.

I'll need to see the imageset xml file and, at least the relevant portion of, the texture file to have any more of an idea.

No need, I found out that autoscaling was set to true on the imageset. Set it to false and it looks fine now.

Thanks anyways
