bad bump edges GPU CUDA/openCL

[Karonte]

Hi All. I think i found a problem in cuda/openCL GPU.
when i load a map... i can se the EDGE of the map. The edge is in the bump map i think. the bump map is a simple jpg so no 16/32 bit, ec...
As you can see in the attachment.
In one image I exagerate the effect in a crop. In the other the effects is quite visible. but there is.

there is somthing to set in the parameters? like gpu texture size, ec...?

NB: The normal rendering ( or RT cpu render) HAS not this artefact.

welll i made another test and it seems that if choose "8bit" instead of "float" in the gpu option...the hard edges disappears...
can someone confermate?
