some image thumbnails are shown with a black border, some are not

[Teo]

See the screenshot. Some image thumbnails are shown with a border, some are not.

I guess having or not having a frame is a matter of tastes, I can't tell which is better, but there's no reason why some images should have a frame and some should not.

Note that some of the tiff images in the screenshot have a border, some don't, so it's not the image format. Also, all the tiffs shown have an alpha channel and all of them have a transparent background, but still some of them have a border and some don't.

I've seen a few bugs reports about thumbnails having or not having a frame, but they either don't mention the coexistence of images with and withoit frame or are marked as fixed.

Do you still that issue in newer versions?

Ubuntu 11.10 (oneiric) reached end-of-life on May 9, 2013.

This issue has sat incomplete for nearly four years.
Reporter doesn't seem to use Launchpad any more.

I'm closing this as 'Invalid' as there was no response to
comment #3, the upstream report doesn't show the problem
as being fixed and we have no way of knowing if the
reporter still sees the problem which may be Unity related.
