I've added you to the developer forums white list and moved this message to the CodeXL forum.
This is a bug in CodeXL( I have experienced the same issue), The issue manifest itself for all non 2D texture and by that I mean your regular 2-dimensional texture. I've seen the issue with cubemaps and volumetric textures.
Thanks for this report. This is indeed a confirmed bug in CodeXL 1.9 and earlier versions. It will be fixed for the upcoming CodeXL release.
