This is not a local error, and it afects several types of machines and/or vídeo cards... The bug exists...
My roomie and I have the same problem with Esseles, it happens about 95% of the time. However, we have two completely different rigs, so someone saying, "it's just one model of one brand..." is blowing smoke up their ***.
Anyway, I don't expect this to be fixed, so I just skip Esseles now.
