Short description of error
Bump map drawing looks very strange. It is pixelated and if I move the view the bump map is very blured and I can not see any details. The wheird thing is that normal maps work perfectly. I do not know if it is only happening on my system.
Exact steps for others to reproduce the error
Just assign a bump map to the default cube. For the case the problem does not happen I included a screen shot into the blend. file. Just notice that you can not see the problem as well because the view is static.
