High Pass Live Filter causes Distortions, 1.9.0.869

[altae]

I wanted to use the High Pass Live Filter to apply High Pass Sharpening to a photograph. Unfortunately there seems to be something wrong with this Live Filter as it introduces distortions when merged to a new layer or when exported. The attached screenshots as well as an exported image should clarify what I mean. There are no distortions introduced with the standard High Pass Filter.

Looks like it has something to do with OpenCL hardware acceleration. As soon as I disable it the distortions are gone (when merging layers as well as when exporting). And it seems I'm not the only one who has been experiencing such issues with OpenCL:

Btw I changed the title as the issue is still present in the latest beta.

I don't know your computer specs but here it works without any problem.
